|Aadra Bhatt||Medicine||Translational||Yesfirstname.lastname@example.org||Gut bacterial metabolism of host endobiotics and xenobiotics, and impact on the intestinal epithelium||Dr. Bhatt has studied the interplay between persistent microorganisms and the host in a variety of physiologic contexts. As a graduate student, she discovered the mechanisms by which a persistent oncogenic herpesvirus induces cancer by reprogramming host cellular signaling and metabolism. During her postdoctoral training with Dr. Matthew Redinbo, she worked alongside structural and chemical biologists to uncover mechanisms by which the intestinal microbiota impacts the incidence and progression of cancer, and how microbial enzymes alter the therapeutic efficacy of anticancer compounds. In collaboration with Dr. Nancy Allbritton, she has developed tools to study host- microbe-drug interactions ex vivo using organotypic cell culture platforms. As a new Assistant Professor at UNC, she is combining her multidisciplinary training to uncover reciprocal interactions between the intestinal microbiota and pharmaceutical compounds, and their implications on host gastrointestinal health.
Dr. Bhatt’s multidisciplinary research combines the diverse disciplines of chemical and structural biology to study how intestinal microbiota can alter the metabolism of various pharmaceutical compounds, and the resultant effects on the intestinal epithelium. By including gnotobiotic mouse models of inflammatory bowel disease, in addition to wild type mice, Dr. Bhatt is executing granular and mechanistic studies of host-microbiota interactions, and how they impact gastrointestinal health.
|Adam Kimple||Otolaryngology/Head and Neck Surgery||Translational||Yesemail@example.com||Chronic Sinsusitis||The sinonasal mucosa is a unique microbial rich interface between the external environment and the immune system, olfactory cortex, and respiratory tract. Mucociliary clearance is an elegant and dynamic process that allows clearance of debris-laden mucus from the sinonasal tract. In the genomic era of medicine, our pharmacological modulation of the sinonasal mucosa has not evolved substantially from steroids, antibiotics and saline lavages. Despite the shortage of modern therapies, the sinonasal mucosa is a uniquely druggable target, amenable to both topical and systemic methods of delivery. I am interested in understanding the differences in male and female sinonasal mucosa and mucus.
|Ajay Gulati||Pediatricsfirstname.lastname@example.org||Microbial influences in inflammatory bowel diseases||My lab is interested in developing safer therapies for the treatment of children with inflammatory bowel diseases (IBD). Presently, most medications used to treat these patients rely on suppression of the immune system and have a high potential for side effects. However, the immune system is only one of the factors that drives intestinal inflammation in IBD. Both the gut microbiota (the normal bacteria that live in our gut) and the intestinal epithelium can modulate host inflammatory responses. One cell type that lies at the intersection of the gut microbiota and the intestinal epithelium is the Paneth cell. These are intestinal epithelial cells that secrete natural antibiotics known as antimicrobial peptides (AMPs). AMPs, in turn, are able to modulate gut bacterial communities. Our overarching hypothesis is that augmenting Paneth cell function will help control gut bacterial communities to reduce chronic intestinal inflammation. To test this hypothesis, we utilize specimens from 2 sources: 1) Genetically-engineered mice that are susceptible to intestinal inflammation; and 2) Tissue and stool specimens from children with IBD. Interestingly, we have found that both susceptible mice, and IBD patients have Paneth cell abnormalities that our lab is in the process of characterizing. We expect this work will lead to novel, minimally-toxic therapies for IBD.|

Local food systems and food access.||Design and testing of innovative clinical and community-based nutrition and physical activity intervention approaches for chronic disease risk reduction in primarily low income and minority populations. Dr. Ammerman has strong research and practice collaborations across the state addressing childhood obesity and was appointed by the Lieutenant Governor to serve on the Childhood Obesity Study Committee, charged with recommending legislative action around childhood obesity. She is also PI of the Center of Excellence for Training and Research Translation, charged with identification, translation, and dissemination of evidence-based interventions for obesity and cardiovascular disease control and prevention. More recent research interests focus on school nutrition policy associated with childhood obesity, sustainable agriculture as it relates to improved nutrition, and social entrepreneurship as a sustainable approach to addressing public health concerns.|
|Alison Stuebe||Obstetrics & Gynecologyfirstname.lastname@example.org||The psychobiology of pregnancy, lactation, and mother-infant attachment||My research focuses on mechanisms of maternal-infant interaction, with an emphasis on lactation and postpartum depression. In the Mood, Mother and Infant study, we are quantifying the role of oxytocin and HPA-axis dysregulation in postpartum depression and impaired mother-infant attachment. Our hypothesis is that PPD is associated with reduced oxytocin and maternal HPA axis dysregulation. These changes reduce maternal sensitivity, impairing dyadic development and increasing risk for insecure attachment. Participants join the study in the third trimester of pregnancy, and mothers and infants present for lab visits at 2, 6 and 12 months postpartum. Medical students have the opportunity to participate in study visits at the MotherInfant Biobehavioral Lab, working with mothers and infants to collect biological samples, heart rate variability data, and videotaped mother-infant interactions.|
|Amir H Khandani||Radiologyemail@example.com||PET Imaging||I am an expert in positron emission tomography (PET).

|Amy Shaheen||Internal Med-General firstname.lastname@example.org||quality and safety in primary care||The quality of care that one receives is variable. Some of the determinants of health include race, gender, socioeconomic status and education. Unfortunately, sometimes it also depends on where and by whom one gets care. Even within our system we see huge variations in care. I have been working for the last few years on decreasing variation in primary care. We have done that in a number of ways, including establishing registries, developing electronic health alerts, and engaging in quality improvement work. Some of the recent projects with which I have been involved include studying the variation of care in benzodiazepine and narcotic prescribing in the UNC IM clinic, decreasing variation of care in acute low back pain, and reducing variation in the pre-authorization process.
While quality improvement research is not new, our understanding of what makes a project sustainable is less so. The current project will look at factors that determine a sustainable project in 10 practices. The project will involve surveying participants, evaluating QI data, and creating a checklist to be passed to the next group working on a QI project in the practice. While \"hand-off documents\" have been used for patient care, they have not been tried for QI. The study will involve identifying key elements and getting feedback from participants. We will also have access to the QI data through the primary care collaborative for the practices where the participants will do their QI work. This data will help determine success of the projects.
|Amy Weil||General Mediicine & Clinical Epidemiologyemail@example.com||Projects involving depression in primary care, humanism in medical education and intimate partner violence||Currently we are reviewing and improving our Depression Screening and Treatment Program in our Internal Medicine Clinic and are working on projects to do so, leading to publication, including developing an anxiety screening and treatment program. We have also recently added a psychiatrist consultant and will be looking at how she assists us with complex patients.
I am currently working to expand humanities education for medical students and there may be opportunity to develop programs/analyze reflective writing pieces leading to publication.
Finally, we are working on initiatives to improve our detection of both depression and intimate partner violence in our Latino clinic.
A later project may involve detection of human trafficking victims in Latino clinic and elsewhere in our hospital and community.
|Andrew Wang||Radiation Oncology Nanomedicinefirstname.lastname@example.org||Nano-and Translational Medicine||My research focuses on applying advances in nanotechnology and biomedical engineering to oncology. Our current research directions are (1) utilizing nanoparticle therapeutics to improve chemoradiotherapy treatment of cancer, (2) tissue engineer ex vivo liver and lung metastases for cancer research studies.
Nanomedicine is a relatively new branch of science that holds high potential in improving the treatment of many diseases, including cancer. Nanoparticles preferentially accumulate in tumors and there is high interest in developing nanoparticle drugs for cancer treatment. There are many nanoparticle drugs in clinical development. My lab develops novel formulations of nanoparticle drugs and evaluate them in animal models of cancer. We also work with commercial formulations (from companies) to obtain the preclinical data for future early phase clinical trials. Our work is very translational and innovative. We have filed 3 patents in the last two years.
Our other research direction is to engineer ex vivo models of cancer metastasis. We collaborate with Dr. Lola Reid and have developed a new liver metastasis model.
I am looking for hardworking students who want to challenge themselves with cutting edge science. Hardwork will be rewarded with co-authorship on manuscripts.
|Andrey Bortsov||Anesthesiologyemail@example.com||Genetics and epigenetics of post-traumatic pain||We employ a variety of computational and statistical approaches to identify genetic and epigenetic predictors of chronic musculoskeletal pain after trauma. Those include analyses of genetic polymorphisms and genome-wide DNA methylation.

|Anna D. Vergun||Orthopedics||clinical||no||Anna_cuomo@med.unc.edu||Prospective, observational study on postoperative pain medication use in children following orthopedic trauma surgery: are we prescribing too much ?||This will be a prospective, observational cohort study to determine how much pain medication is being used by children following surgical treatment of common pediatric fractures. The common practice amongst surgeons is to prescribe at least a week supply of narcotic pain medication for children after surgery, however, it is the author\'s experience that most children require only one or two days of medication and most do not require narcotics. We plan to enroll patients immediately after their surgery and follow them with phone calls at home during the first postoperative week to determine their pain levels and pain medication requirements. We hope to better understand postoperative pain in this cohort and offer surgeons better guidelines for prescribing narcotics.|
|Anthony Charles||Surgeryemail@example.com||Predictors of Mortality and other outcome measures in Trauma Patients||The purpose of this study is to ascertain risk factors for death from trauma. The large cohort allows for simultaneous evaluation of known mortality risk factors along with controlling for factors to assess the influence of each independently. Individually, base deficit, temperature, hypotension, age, and injury severity have been shown to be associated with an increased risk of death. However, in the English literature, there is no data on the independent predictive power and interaction of these risk factors.
Other outcome measures we are studying include, Hospital Length of stay, Intensive care unit length of stay. discharge destination and complications
In addition, as we have an aging population we are proposing to look at the influence of pre-existing cormorbid diseases on trauma outcome using the Charlson Co-morbidity Index.
The state of North Carolina has a developed trauma system, with hospitals with varying trauma verifications and capabilities. We are interested in the mortality effect of direct transportation of a trauma victim to a trauma center as opposed to transfer to the nearest hospital.
Data sources available for use include: National Trauma Data Bank (NTDB), North Carolina Trauma Registry and the University of North Carolina Trauma Registry.
|Ari Isaacson||Radiologyfirstname.lastname@example.org||Embolization and Advanced Vascular Imaging||My interests lie in utilizing embolization to treat common conditions in a minimally invasive manner. I am currently the PI for pilot studies evaluating prostatic artery embolization to treat BPH and geniculate artery embolization to treat knee pain secondary to osteoarthritis. I am slo interested in studying how to use advanced imaging tools for pre-procedural planning in order to make interventional radiology procedures safer and more efficient.|
|Arlene Davis||Bioethics||Basic||Noemail@example.com||clinical ethics in intensive care units||The MICU Burnout Study team (Hitesh Patel, MD, PI; Kunal Patel, MD; Jean Cadigan, PhD; Arlene Davis, JD, and others) is conducting an IRB-approved mixed methods study in the UNC Medical Center MICU to explore how resident burnout arises in this unique setting in order to: (1) identify drivers of burnout specific to the MICU; (2) identify interventions to improve the MICU experience; and (3) provide the best educational experience possible for the variety of residents who rotate through the unit. Because burnout is often accompanied by moral distress and ethical conflicts and impacts patient care, practical ethics can offer an important perspective in data collection, analysis, and development of interventions. A medical student working with the interdisciplinary team during Summer 2022 could participate in (1) analysis of the various survey, interview, and focus group data collected to date, (2) further literature review in intervention design and testing, and (3) initial pilots of various interventions.|
|Asheley Skinner||Pediatricsfirstname.lastname@example.org||Child Maltreatment||We do a variety of research related to child maltreatment and, specifically, the Child Medical Evaluation Program. I am a PhD Health Services Researcher who works with MDs and other clinicians. Our goals are to improve the quality of medical evaluations of children with suspected maltreatment.
We are currently working on a project examining long bone fractures in children and the usefulness of skeletal surveys to identify other injuries.
Although the skeletal survey project is a current priority, I have many additional projects and interests, including child maltreatment, obesity, injury prevention, and substance use.

|Balfour Sartor||Gastroenterology & Hepatologyfirstname.lastname@example.org||Host/Microbial interactions in intestinal inflammation and homeostasis||The major focus of Dr. Sartor`s laboratory is to better define the role of commensal enteric bacteria in mediating immune-mediated chronic intestinal inflammation vs. mucosal homeostasis in genetically susceptible vs. resistant hosts, respectively. This research employs gnotobiotic rodent models in which the enteric bacteria can be precisely manipulated, using the National Gnotobiotic Rodent Resource Center (P40 RR018603) that he directs. Primary models are IL-10 deficient mice colonized with E. coli and Enterococcus faecalis and isogenic mutants of these species in which various bacterial virulence genes have been deleted to determine their functional role (RO1 DK 53347) and HLA B27/Ã¯Â¢2 microglobulin transgenic rats colonized with Bacteroides vulgatus and other Bacteroides species (RO1 DK40249). In vitro mechanistic studies complement these in vivo investigations. These investigations explore both host and bacterial factors that mediate inflammation vs. homeostasis, particularly host immunoregulation and commensal bacterial virulence genes and the effect of inflammation on bacterial gene expression. Additional funded studies investigate the mechanisms by which diet, particularly dietary iron, aluminum and sucrose, potentiates experimental intestinal inflammation, exploring the effect of dietary components on enteric bacterial composition and gene expression (Crohn`s and Colitis Foundation of America Senior Research Award), the role of dietary iron on Bacteroides fragilis function (R21 AI079183), the role of enteric bacteria and bacterial TLR ligands on hepatic fibrosis and neoplasia (RO1 DK 076920), the therapeutic potential of probiotic bacterial species on hepatic inflammation and fibrosis (R21 AT003878) and the role of enteric bacteria and bacterial components on radiation-induced intestinal injury (U19 AI 067798).|
|Boyce Griffith||Otheremail@example.com||Computer modeling and simulation of cardiovascular function and dysfunction||Our research focuses on mathematical modeling and computer simulation of cardiovascular function and dysfunction. Research topics include fundamental research on methods to enable physiological simulation, tools for medical image-based model construction, and applications in physiological simulation. This research falls within the scope of mathematical and computational biomedical engineering. We are actively working to develop computer simulation-based tools for modeling medical devices. For instance, with UNC clinicians, we are actively developing computer models of transcatheter aortic valve replacement (TAVR) devices that can assist in device selection and device design. We envision that similar models will also be developed for emerging transcatheter devices for mitral valve repair and replacement. We are also developing computer models of cardiac electro-mechanical coupling that can be applied to cardiac resynchronization therapy (CRT). Finally, we are beginning work in collaboration with researchers at the FDA to simulate the performance of vena cava filters, prosthetic heart valves, and ventricular assist devices. We aim to demonstrate that our simulation tools are capable of providing regulatory grade evidence for a range of cardiovascular devices. Doing so will require careful validation using both in vitro and in vivo models.|
|Brian Button||Medicine / Marsico Lung Institute||Translational||Yesfirstname.lastname@example.org||Airway biology in health and disease||The goal of my research is to understand how altered mucus properties are responsible for reduced airway clearance rates in persons with muco-obstructive lung diseases, including chronic bronchitis, asthma, and cystic fibrosis. To address these questions, we develop and utilize novel approaches to investigate the biochemical and biophysical properties of airway mucus. As a model system, we utilize both in vitro cell culture models of the human airway, as well as freshly excised tissue from chronic bronchitic and cystic fibrosis lungs. From a therapeutic point of view, we are working to identify putative rehydrating and mucolytic agents which can make mucus flow better, and thus, stimulating clearance in patients with these life-altering diseases.|
|Brian Diekman||Biomedical Engineering||Translational||Yesemail@example.com||Cartilage aging and regeneration||This project utilizes animal models (mouse and rat) to understand the role of aging in limiting the potential for cartilage regeneration. The inability of cartilage to heal effectively after injury is one driver of the development of osteoarthritis. There is evidence for regenerative potential in immature cartilage tissue that is lost upon maturity. Our hypothesis is that signals present in mature cartilage limit the proliferative capacity of chondrocytes. By altering the signaling pathways through genetic manipulation, we hope to identify targets for therapies that would not only boost cartilage regeneration but also protect tissue from the effects of aging that predispose cartilage to become dysfunctional during aging.|
|Carlton Zdanski||Otolaryngology Head & Neck Surgery||translational||no||zdanski@ med.unc.edu||Predictive Modeling for Treatment of Upper Airway Obstruction in Young Children||The project will examine computational fluid dynamic modeling of the pediatric airway in a multi-pronged effort to produce new tools to evaluate the pediatric airway and to create computer models which allow physicians and scientists to predict which medical or surgical intervention is most appropriate in specific children and with specific disease states. This study specifically examines infants and children up to 10 years old with Pierre Robin sequence (a condition characterized by small jaw and posterior displacement of the tongue causing airway obstruction) and subglottic stenosis (narrowing of the airway below the vocal cords), but the tools developed may be more applicable to other airway problems as well.
The three co-principal investigators of the R01 grant, awarded by the National Institutes of Health, are Stephanie Davis, MD, Chief of Pediatric Pulmonology in the School of Medicine, Carlton Zdanski, MD, Chief of Pediatric Otolaryngology/Head and Neck Surgery and Surgical Director of the North Carolina Children\'s Airway Center, and Richard Superfine, PhD, Professor and Director of the NIH Center for Computer Integrated Systems for Microscopy and Manipulation in the Department of Physics and Astronomy in UNC\'s College of Arts & Sciences.

|Celia Shiau||Biology and Microbiology & Immunology||basic||Yesemail@example.com||Macrophage, Inflammation, Neuroimmunology||Development and function of tissue-resident macrophages
Macrophages are highly dynamic and widespread blood cells that play many important functions in vertebrates. They are the main phagocytes throughout the body, responsible for clearing away dying cells, damaged tissue, and pathogens, to maintain tissue integrity. Macrophages circulate in the bloodstream as monocytes or are stationed in strategic locations of the body as tissue macrophages where their phagocytic roles are critical, such as microglia in the brain, Kupffer cells in the liver, Langerhans cells in the skin, and osteoclasts in the bone. Overall, the developmental process by which macrophages take residence and differentiate into tissue macrophages remains poorly understood. We are currently investigating the transcriptional and cellular regulation underpinning the differentiation of the diverse tissue macrophages.
Cell-cell interactions between macrophages and other systems
The influence of macrophages on the development and homeostasis of various organs can be far-reaching. Yet the normal roles and mechanisms of macrophages and microglia in the healthy body and brain, respectively, remain far less understood than their functions in disease and injury. Of particular interest is the function of microglia in the healthy brain. Although not well understood, they have been implicated in shaping brain circuitry and neuronal development as well as in possibly affecting behavioral outcomes. We are also focusing on the critical role of macrophages in preventing inappropriate activation of inflammatory processes that would otherwise damage healthy tissues. We are addressing fundamental areas of macrophage biology in the context of how macrophages participate in the nervous system as well as other areas of the body prone to inflammation.

|Chris Dekaney||Surgeryemail@example.com||Role of Paneth Cells in damage repair.||Paneth cells make up part of the intestinal stem cell niche. Following damage we observe that the number and size of Paneth cells within this niche increase during regeneration concomitant with intestinal stem cell expansion. This lead us to ask why this increase in Paneth cells occurs and how this increase occurs. To these ends, we are investigating the roles Paneth cells play in intestinal regeneration and the mechanism(s) involved in expansion of the Paneth cells during repair. Understanding these areas will allow us to have a better understanding of the intestinal stem cell niche during repair, but will also provide us with valuable insight in how to control Paneth cell numbers and potentially Paneth cell secretory products. Participation in this project will provide students with exposure to molecular biology, histology, cell culture, microscopy, proteomics and data analysis.|
|Chris Dekaney||Otherfirstname.lastname@example.org||Mechanisms and Function of Paneth Cell Expansion After Doxorubicin-Induced Damage||While the intestinal epithelium has a remarkable capacity to repair and regenerate after injury, our understanding of underlying mechanisms of epithelial repair is incomplete. Intestinal stem cells (ISC) play a central role in repair of intestinal epithelium following damage and are under the influence of numerous factors which make up the ISC niche such as Paneth cells (PC) which reside at the base of small intestinal crypts intercalated among ISCs. This places PCs in an advantageous position to influence ISCs impacting survival, proliferation or cell fate decisions during epithelial repair. We recently reported dramatic PC expansion, associated with ISC expansion, in mice following intestinal epithelial injury by the commonly used chemotherapeutic drug, doxorubicin (Dox). Students involved in this project will take part in defining the mechanisms and mediators of PC expansion and the functional significance of PC expansion on enteric microbiota and ISC expansion following the damaging effects of chemotherapy on the intestinal epithelium. Students will be exposed to molecular biology (PCR, protein electrophoresis), histology and morphometry, cell culture, and flow cytometry.|
|Chris Mack||Pathology & Laboratory Medicineemail@example.com||Vascular disease and hypertension||Although we are interested in many areas of cardiovascular physiology and pathophysiology, much of our work revolves around the question of how changes in gene expression in vascular smooth muscle affect the development of cardiovascular disease. Major projects include;
1)The genetics of hypertension â€“ With the help of our clinical and bioinformatic colleagues, we generate and analyze genetic, gene expression, and clinical data sets to identify the mechanisms by which common genetic variations control vessel contraction, blood pressure, and the development of hypertension.
2)The epigenetic regulation of contractile gene expression in vascular smooth muscle â€“ We use a variety of genome-wide approaches to identify the enhancer elements, transcription factors, and chromatin modifiers that drive the SMC-specific expression of many contractile genes.
3)Cytoskeletal and contractile signaling in vascular smooth muscle â€“ We continue to characterize the RhoA-mediated signaling mechanisms that control actin polymerization, actin-myosin-based force generation, and myocardin factor nuclear localization in smooth muscle.

The goal is to get preliminary data for the development of a risk calculator for UTI in nursing home patients. We will be going to the sites and doing chart reviews at the 4 sites once a month over the course of the summer. Each NH may require two days to do the chart reviews, depending on the number of U/As and cultures done. The project includes chart review, data collection, and data entry. I will provide mentorship through the process and the student will be assisted in submitting an abstract for AGS and co-authoring a manuscript.

|Claire Doerschuk||Medicine||basic||Yesemail@example.com||Leukocyte function in pneumonia and acute lung injury||Dr. Doerschuk's research interests address host defense mechanisms in the lungs, particularly the inflammatory and innate immune processes that are important in the pathogenesis and course of bacterial pneumonia and acute lung injury/acute respiratory distress syndrome. Basic and translational studies address the mechanisms of host defense during pneumonia in response to bacterial and viral pathogens that cause common and clinically important community-acquired and nosocomial pneumonias. Her focus is in the mechanisms of leukocyte recruitment and function, particularly neutrophils and macrophages, neutrophil-endothelial cell interactions, and effector functions of neutrophils during inflammation and innate immune responses in the lungs. Studies of leukocyte kinetics include neutrophil production and release from the bone marrow and their sequestration, adhesion and migration into lung tissue. More recently, her studies address leukocyte kinetics, immune responses and host defense following exposure to combustion products from burn pits. The ultimate goal is to utilize this knowledge to develop therapies that enhance the inflammatory response when it is beneficial to the host and dampen this response when it is harmful.|
|Clare Barrington||Public Healthfirstname.lastname@example.org||HIV/AIDS prevention||The overall goal of my research program is to examine social and contextual influences on health and health behaviors to inform the development of culturally relevant population-level public health policies and programs. I draw on theories from across the social sciences and use a combination of qualitative and quantitative methods. I am particularly interested in examining the influence of social networks on sexual risk behaviors and how networks can be used as effective tools for HIV/AIDS prevention. Most of my research is in the context of concentrated HIV epidemics of the Caribbean and Central America, in particular the Dominican Republic where I have several ongoing collaborations. In addition to my work in the Dominican Republic, I am collaborating with researchers from the Center for Disease ControlÃ¢â‚¬â„¢s Global AIDS Program in Guatemala on two studies with men who have sex with men: the first is a comparison of sampling strategies used to obtain population estimates of HIV prevalence and the second is a formative evaluation of sexual health services for this population.

|Crystal Schiller||Psychiatryemail@example.com||Neuroendocrinology of Reproductive Related Mood Disorders||My research focuses on the influence of sex steroids on brain function and affective regulation in women. I currently am conducting two NIH-funded projects in this area: First, we are examining the effects of a scaled-down hormonal model of pregnancy and parturition on neural reward processing, affective processing, and depressive symptoms in women with and without a history of postpartum depression (NIMH R21). Second, I am measure activity in the neural reward system in perimenopausal women with and without MDD using functional magnetic resonance imaging (fMRI) at baseline and following estradiol treatment (NIMH K23). In addition, I am collaborating on NIH and foundation-funded projects examining 1) stress physiology in premenstrual dysphoric disorder, 2) hormone influence on eating pathology in perimenopausal women, 3) genetic biomarkers of perinatal mood and anxiety disorders, and 4) acceptance and commitment therapy group treatment for perinatal women with mood and anxiety disorders. Ultimately, I hope my primary line of research will 1) advance our understanding of the effects of ovarian hormones on the brain and how these effects contribute to the triggering of and susceptibility to mood disorders in women; and 2) help to identify neural and endocrine markers of depression risk, thereby improving our ability to predict illness onset and develop novel approaches to prevention and treatment.|
|Crystal Wiley Cene||Medicine||Translational||Yesfirstname.lastname@example.org||Patient and Family Engagement in Heart Failure Care||Close to 40% of older adults in general and heart failure patients specifically, are accompanied to medical visits by a family member. These family members are very influential in supporting patients as they manage their heart failure, yet their contribution is often under-appreciated by health care providers. The quality of communication between patients, family members, and health care providers greatly influences how well heart failure patients take care of their illness at home (i.e. self-management). Our prior study demonstrated, using analysis of audiotaped data from actual visits, that heart failure patients and family members are not actively engaged during visits, as indicated by asking fewer questions and giving less information. This is disturbing given known knowledge deficits among heart failure patients and family members about heart failure.
Strategies such as pre-visit prompt lists can enhance engagement by encouraging patients and family members to ask relevant questions and discuss sensitive topics with health care providers. A prompt list is a structured list of questions or topics related to illness, treatment, and support that is developed from interviews with patients, family members, and health care providers. Prompt lists are completed by patients and family members before a visit. Prompt lists have been shown to increase the number and relevance of questions asked by patients and family members. However, several important gaps in the literature exist. First, the effect of prompt lists on self- management behaviors has not been tested. Second, few studies have used them with family members. Lastly, prompt lists have not been tested in heart failure patients. Most of the research on their use has been conducted in cancer patients facing oncology-specific clinical decisions. To address these gaps, we developed a pre-visit prompt list for use with heart failure patient-family member dyads (using cognitive interviews). We are currently conducting a pilot randomized trial in 30 heart failure patient-family dyads. We randomize participants to receive the prompt list vs. usual care and assess feasibility, acceptability, and effects on behavioral outcomes.
A student participating in this project would have the opportunity to assist with: data collection in the clinic and writing abstracts and manuscripts to be submitted for publication (on which the student could be a co-author). The student could also have the opportunity to work on other related projects lead by Dr. Cene focused on developing practical tools to enhance engagement among patients with multiple chronic conditions and their family members.

We have identified stem cell sub-populations from both the liver and pancreas that can potentially differentiate to mature cells. By integrating novel technologies from the area of tissue engineering we have placed an emphasis on developing the matrix or template that would support the growth and differentiation of selected stem cell populations into functional tissues. This effort is impacted to factors including ischemia-reperfusion as it relates to cell recovery, proliferation and differentiation. A complementary arm of our experiments includes the study of the immune responses as they potentially affect the development of these novel organs-tissues.
We have been analyzing cell signaling pathways that are critical to hepatic progenitor cell proliferation, survival and subsequent death. This has involved a series of experiments focused on the cellular niche (including the extracellular matrix and cytokines present in the cellular microenvironment).
We are currently studying the presence of a persistent pancreatic progenitor-stem cell population beyond the fetal stage in both human and animal models.
We are currently working on incorporating microfluidics in the design of an bioartificial organ device that would have both in vitro and in vivo applications.

We are testing this hypothesis by examining how disrupted primary cilia signaling affects the formation and function of neuronal circuitry, dysfunction of which is widely implicated in the pathophysiology of neurodevelopmental disorders. We employ a powerful combination of mouse genetics, electrophysiology, in vivo live cell imaging, behavioral assays, and chemogenetic manipulation of ciliary signaling to decipher the convergent mechanisms underlying neuronal connectivity. By determining the changes in cortical neuronal connectivity and function following primary cilia dysfunction, in the context of patient mutations in ciliary genes associated with neurodevelopmental disorders, the outcome of these studies will help pinpoint the signaling pathways highly relevant to circuit malformations in neurodevelopmental disorders.|

The risk of venous thrombosis or venous thromboembolism (VTE) increases as we age, although the precise mechanism is not known. Expression of the tumor-suppressor gene p16ink4a (p16) increases with age and is associated with cellular senescence. However, it is not known if p16 is involved in the relationship between aging, senescence and the increased risk of venous thrombosis. We are testing a hypothesis that senescence (and aging) is associated with impaired hemostasis and will contribute to a prothrombotic phenotype. We are performing several different studies: (a) transgenic mouse model of p16 over-expression has a mild prothrombotic phenotype; (b) aged mice (1.5-2 years old) naturally up-regulate p16 expression and show age-related senescence; (c) in vitro model of human endothelial cell expression that become senescent (with several compounds used in drug-coated stents that promote localized cellular senescence); and (d) we would like to gather translational data regarding p16 expression linked to the risk of deep vein thrombosis. The contribution of senescence in the vasculature to the age-associated risk of venous thromboembolism is still a new field. We are beginning to better understand the role of cellular senescence linked to arterial disease occurrence; by contrast, we understand very little about the influence of senescence to venous thromboembolic diseases. Thus, we are trying to better understand the pathophysiological link between the occurrence of VTE with age and senescence.|

Compared to the general arterial-venous and lymphatic circulations, much less is known about collateral vascular biology. For example, until our work nothing was known about when or how these unique anastomosing vessels form or the molecular mechanisms involved. We have that discovered that these vessels form late in gestation after the general and lymphatic circulations have become established. Our studies have also found that the extent (ie, density, diameter, lengthâ€”thus conductance) of the native pre-existing collateral circulation in healthy individuals (inbred mouse strains) varies dramatically from naturally occurring genetic polymorphisms, and showed that these differences have a major impact on tissue injury and collateral flow recovery in mouse models of occlusive disease, including middle cerebral artery occlusion. We have also identified the first two genes (Vegfa and Clic4) whose expression significantly impacts formation of the native collateral circulation, and have used quantitative trait loci and SNP association mapping to identify additional candidate genes responsible for genetic variation in extent of the collateral circulation. Besides genetic factors, we are also studying the effect of environmental factors, disease risk factors, and gene-environment interactions for adverse effects on formation and maintenance of the collateral circulation in utero, perinatally,and during growth to adulthood and thereafter, as well as effects on extent of collateral remodeling in occlusive disease.

|Jean-Claude Mwanza||Ophthalmology||Clinical||Nofirstname.lastname@example.org||Comparison of Visual Field Using a Tablet-based Perimeter and Humphrey Field Analyzer||BACGROUND
Glaucoma is the second case of blindness worldwide. It is a slow progressive neurodegenerative disorder affecting the optic nerve. It is characterized by the dysfunction and then death of retinal ganglion cells (RGCs) and their axons, leading to morphological changes to the optic nerve head (ONH) and visual field deficits. If left untreated or inadequately treated glaucoma slowly leads to irreversible blindness. Both medical and surgical treatment are effective in controlling intraocular pressure (the main risk factor) in most cases and slow considerably the progression of the disease and therefore prevent visual impairment. In the United States, the number of people with glaucoma rose from 2.2 million to 2.7 million from 2000 to 2010, with projections to increase to 4 million in 2030 and 6.3 million in 2050. The prevalence of glaucoma varies across regions, but it is highest in Africa[2-6] More importantly, of all people with glaucoma in the United States, approximately 50% are undiagnosed. Such rates are even higher in low-income countries. In sub-Saharan Africa for example, 87.1% to 98.5% of people with glaucoma diagnosed in population-based surveys were not aware that they have it.[5-11] Thus the key to preventing visual impairment and its consequences such as falls, bad quality of life, is early detection of glaucoma, particularly in populations at risk.
There have been several attempts to develop glaucoma screening various methods such as those focusing on intraocular pressure measurement, appearance of the optic nerve head or questionnaires, but those methods proved to be less sensitive and less specific. Because glaucomatous visual field deficits are specific, a screening method based on visual field testing may help detect glaucoma in population at risk.
However such a screening cannot be performed using the method of visual field testing used in the clinical setting (Humphrey Field Analyzer, HFA) because it is time-consuming. A good method screening method should be inexpensive, portable, easy to use, administer, and interpret, and comfortable for the subjects.
TestFlight is a tablet-based application called MRF for Melbourne rapid Field on the iPad platform that has been developed with the ultimate aim of facilitating perimetry outside the traditional clinical setting. It features a blind spot monitor, reliability tests, and fast thresholding using Bates logic. It provides the same testing modes and outputs as the HFA. In addition to the test pattern used on HFA (which allows comparison), it also has its own specific testing pattern with more test points. It is easy to use, it only take about 2 minutes per eye. Prior to using it in population screening, it needs to be tested in clinic to see how it performs in real glaucoma patients
1) To compare the perimetric results from the iPad-based app (Melbourne Rapid Fields or MRF) to those of HVF 24-2 SITA Standard testing mode.
2) To evaluate accuracy of the MRF, an iPad app, for performing perimetric screening
3) To correlate the results of MRF and HFA.
Consecutive patients attending their clinical appointment in the glaucoma clinic and scheduled for HFA will be recruited for the study. They will qualify for the study if they are at least 18 years old, have diagnosed with glaucoma in at least one eye, are willing to perform the tablet-based visual field prior of following the HFA, have best corrected visual acuity of 20/40 per qualifying eye. Patients with diabetic proliferative retinopathy, neurological disorders, or those on medication that may affect visual field will be excluded. A total of 80 patients with glaucoma at different stages (early, moderate, advanced) will be enrolled in the stud. Each patients will undergo both tests the same day, in no particular order although we prefer MRF first while they are waiting for HFA. 30 0f these patients will also undergo spectral domain optical coherence tomography (OCT) of the ONH and the macula
Because HVF testing is usually performed once a year, patients will be perform both tests a year later the day HFA is scheduled.
Study parameters on both tests will include 1) mean deviation, 2) pattern standard deviation, 3) number of missed locations, 4) false positive rates, 5) false negative rates, 6) time to complete the test, 7) the number of points worse than 5% probability level of total deviation map.
The analysis will include comparison of the study parameters from the two tests (paired t-test) and correlating them (Pearson correlation). Person correction of deviation and pattern standard deviation with OCT parameters ( retinal nerve fiber layer thickness, ganglion cell-inner plexiform layer thickness, rim area, vertical cup-t-disc ratio) will also be performed.

Recently her group identified new subtypes for pancreatic cancer that was published in Nature Genetics. Pancreatic cancer is a particularly difficult cancer to analyze because of its confounding and dense stroma and low tumor content. To solve that problem her group used a computational approach to separate the normal from the cancerous tissue and the stroma. These results help understand some of the controversy in the field regarding pancreatic stroma and will set the groundwork for future clinical trials, allow treatments to be assigned based on the subtypes, and guide the development of new therapies.

|Jimena Giudice||Cell Biology & Physiologyemail@example.com||Alternative splicing in development and diseases||Alternative splicing is a posttranscriptional mechanism that explains how individual genes can produce more than one transcript due to the inclusion or exclusion of specific regions originating multiple protein isoforms with diverse features. More than 90% of human genes undergo alternative splicing. During development multiple transcriptional networks are coordinately regulated to drive organ maturation, tissue formation, and cell fate.
A wide variety of human diseases are caused by mutations within cis-acting sequences of pre-mRNAs that produce aberrant splicing and alter function of the mutated allele (Duchenne muscular dystrophy, Cystic fibrosis, among others). In addition, certain splice isoforms are depleted or induced in cancer, diabetes, or muscular dystrophies suggesting specific physiological roles. Defects in functions or expression of RNA-binding proteins and core spliceosome constituents induce splicing mis-regulation in multiple severe diseases.
Tissue specific alternative splicing is critical to maintain tissue identity. Brain, heart, and skeletal muscle are the tissues where the most tissue specific splicing takes place raising the questions of: how developmental stage- and tissue-specific splicing influences protein function and how this regulation occurs. To investigate this big-picture question, our research program has three angles:
- the molecular mechanisms that explain how alternative splicing regulates the expression of trafficking and membrane dynamics proteins in normal development and diseases.
- how alternative splicing impacts on the functions of membrane trafficking proteins in internal cell architecture and physiology.
- the roles of epigenetic dynamics on alternative splicing regulation in postnatal striated muscle development.

|Joan Taylor||Pathology & Laboratory Medicineemail@example.com||Development of Human Hypertension; Discovery of Novel Means to Mitigate Cardiac Necrosis||We have two projects to chose from
1) Translational: Although several large GWAS identified a novel locus in the ArhGAP42 gene that was associated with blood pressure (BP), no causal link has been established between these SNPs and the pathogenesis or outcomes of hypertension. Our group has shown that ArhGAP42 is specifically expressed in smooth muscle and negatively regulates BP in mice by inhibiting RhoA activity and that the minor allele at rs604723 was associated with increased ArhGAP42 expression in human arterial samples. Our genotype/phenotype analysis revealed that the minor BP allele increases ArhGAP42 expression and protects against the development of hypertension in Caucasians. Interestingly, the protective allele is under-represented in African Americans. This project we will use DNA samples from case-controlled studies to determine if allelic variations in ArhGAP42 affect genetic risk for hypertension in African Americans and will explore associations with clinical manifestations(i.e. hypertensive arterionephrosclerosis)in both races.
2) Basic Science: Hearts are vulnerable to a multitude of pathological insults including ischemia-induced necrosis. Previously, necrosis was viewed as a passive/irreversible cell death and was ignored as a target for clinical intervention. However, recent work indicates that necrosis is a reversible cell signaling process. We recently performed a novel genome wide siRNA screen to identify new modulators of calcium induced necrosis. This project would focus on determining which of these factors promote survival of cardiomyocytes in response to ischemia in the hopes of identifying new therapeutic targets to treat ischemic heart disease.
|John Vavalle||Cardiologyfirstname.lastname@example.org||TAVR - Transcatheter Aortic Valve Replacement: Improving patient selection and clinical outcomes||Over the last several years, there have been rapid advances in our ability to perform minimally invasive heart valve replacements and repairs using catheter-based devices. Transcatheter aortic valve replacement (TAVR) provides a life-saving procedure for those who are high risk for surgical valve replacement. There is a very large and growing unmet need for percutaneous valve replacement and repair due to the aging US population. Severe symptomatic aortic valve stenosis carries a very poor prognosis without valve replacement. However, many of the patients in need of valve replacement are at high risk for surgery. Therefore, transcatheter aortic valve replacement becomes the best therapy for them.
Since this technology is so new, there are many unanswered questions about the best use of this technology. Complications such as paravalvular leak, heart block, and vascular injury remain a big limitation to this therapy. Much research is needed to best identify which patients will benefit the most from this technology and to improve the application of these new devices. There are robust clinical databases that are stored at UNC and beyond that can be accessed to ask these important questions. Given that this field is so new, the opportunities for research are wide open and a motivated student would be able to lead a research project under the mentorship of the UNC Heart Valve Team.
|Jonathan Berg||Geneticsemail@example.com||Application of genome-scale sequencing to gene discovery and clinical care||As a clinician and researcher, I am deeply interested in the development and application of genetic tests in patients and their families. The recent revolution in genetic sequencing technology has led to an unprecedented opportunity to investigate the underlying etiology in families with genetic conditions, ranging from the discovery of novel disease susceptibility genes in large pedigrees, to the application of genome-scale sequencing in a clinical context.
I am a board certified medical geneticist in the UNC Adult and Cancer Genetics clinic. My clinical effort involves the evaluation of individuals and families with Mendelian disorders, including hereditary cancer syndromes, connective tissue disorders, and other rare genetic conditions. My ongoing research efforts extend directly from my clinical activities.
My laboratory is enrolling probands with a strong family history of cancer but negative results on clinically available genetic tests. We hypothesize that these families harbor rare deleterious mutations in potentially novel cancer susceptibility genes and we are utilizing high-throughput sequencing to identify candidate disease-causing mutations.
I am also co-PI of an NHGRI-funded U01 Clinical Sequencing Exploratory Research (CSER) project called â€œNCGENESâ€ that examines the utility of whole exome sequencing (WES) in a clinical context. This project will examine the diagnostic utility of WES as well as the impact of incidental findings discovered during the course of testing.
Both of these projects provide ample opportunities for students to explore either bench science, informatics approaches, or both.

|Kathleen Caron||Cell & Molecular Physiologyfirstname.lastname@example.org||Genetic Models of Cardiovascular Development and Disease||Adrenomedullin and its receptors are highly expressed in endothelial cells and are required for the normal development of the cardiovascular system, including the heart, lymphatic vessels and placenta. Using a variety of gene targeted animal models we have characterized a novel role for adrenomedullin and its receptors in the development and function of these cardiovascular organs. Our interests in cardiovascular biology are broad and highly integrative, since we have discovered that the functions of adrenomedullin signaling are largely influenced by other angiogenic and endocrine factors, hypoxia and innate immune responses. Therefore, our current studies are geared toward providing novel insights into the complex processes that govern the establishment of lymphatic and placental vascular beds and how perturbations in these specialized vessels can have deleterious consequences such as lymphatic disorders or poor pregnancy outcomes. We are currently focusing on the effects of perturbed lymphatic function on the absorption of lipids from the digestive tract.

|Laurence Katz||Emergency Medicinefirstname.lastname@example.org||Infrared imaging to evaluate resuscitation during shock||Shock is insufficient tissue blood flow (perfusion) and oxygen delivery to body tissues, a leading cause of death from trauma. The decrease in perfusion and oxygen availability result in organ failure or patient death unless perfusion and oxygen deficits are recognized and treated. It is difficult to evaluate if adequate perfusion and oxygen have been restored during resuscitation from shock since there are no reliable methods to detect hypoperfusion or changes to perfusion during resuscitation. Assessments of peripheral circulation have been shown to be indicators of hypoperfusion and shock. However, most measures of peripheral circulation are subjective and difficult to monitor dynamically. Skin temperature decreases as peripheral circulation decreases, but it has not been measured during shock and resuscitation. As a result, we propose to longitudinally measure skin temperature with infrared thermography during shock and resuscitation. We hypothesize that infrared thermography, a non-invasive, non-radiation technology may provide a tool to detect shock and guide resuscitation.|

|Lola Reid||Cell Biology & Physiology||basic||no||Lola.M.Reid@gmail.com||Genetic signatures of stem/progenitor populations in the network for hepatic and pancreatic organogenesis||We have identified maturational lineages of cells emanating from primitive endodermal stem cell populations, biliary tree stem cells (BTSCs), which are found within Brunnerâ€™s Glands, in peribiliary glands (PBGs) throughout the biliary tree, and in the crypts of villi of the gall bladder. They give rise to hepatic stem cells (HpSCs) and hepatoblasts (HBs), located in or near the canals of Hering within liver acini, and to committed pancreatic progenitors in pancreatic duct glands (PDGs) found throughout the pancreas. These in turn give rise to the mature cells of the liver (hepatocytes, cholangiocytes), and pancreas (acinar cells, islets).
The maturational lineages progress along radial and longitudinal axes. The radial axis begins with primitive BTSCs in the centers of bile ducts and transitions to mature cells at the bile duct lumens. The longitudinal axis begins with high numbers of primitive BTSCs within Brunnerâ€™s Glands in the duodenum and in the PBGs in the hepato-pancreatic common duct next to the duodenum, and transitions to mature cells in the liver and along a separate branch to mature cells in the pancreas. The lineages constitute networks of niches that collectively participate in organogenesis for liver and pancreas throughout life. We have identified many of the major stages within the hepatic pathway (at least 10), and we are part way towards defining those for pancreatic fates (so far, at least 7).
We are defining transcriptomic signatures (global RNA-seq analyses) of each of these stages and have done a number, but not all, of the critical ones in the hepatic pathway and, so far, none in the pancreatic pathway. However, we intend to complete the process for all of the major stages and do the initial analyses over the coming year. Given that such transcriptomic signatures will comprise up to 30,000 genes as well as long, non-coding RNAs per maturational stage, it will take longer than the time of this funded proposal to fully understand the resulting data using bioinformatics. However, even the initial studies should enable us to know to what stage(s) the grafted stem cells have matured and for what functions they are capable. Also, from the gene expression landscape in each of the distinct stages, we will learn of signals that might be used to regulate the cells towards full maturity. In addition, in studies completed over the past year, critical changes were identified that can occur with malignant transformation, information important in the design of grafting strategies to avoid such changes.
The hepato/pancreatic organogenesis model systems being used consist of those in mice, humans and pigs. As background, we have characterized basic stem cell and maturational lineage biology in all of these species and established methods of isolation of the relevant cell sub-populations, serum-free, wholly defined organoid culture methods, and serum-free cryopreservation and thawing protocols for organoids and cells. In addition, we have defined the graft composition and the surgical procedures that optimize engraftment into target sites with minimization of complications such as adhesions. We hope to transition within a few months to functional studies to assess the extent to which transplanted stem cells have matured into relevant adult fates. The global transcriptomic studies to be done on freshly isolated cells will serve as the controls for the transcriptomic signatures to be analysed on transplanted cells.
We have organized to obtain â€œenblock tissuesâ€ from human neonatal donors and to consist of the liver, biliary tree (including the gall bladder), duodenum, hepato-pancreatic common duct and pancreas from each donor. By having all of the tissues from the same donor, we will be able to eliminate confounding inter-individual variations. The tissues from at least three human donors will be obtained and, in parallel, porcine tissues, and used by the Reid lab (Drs. Wencheng Zhang and Xianwen Yi, and others) to isolate purified cell populations of the major stages of the hepato/pancreatic network. In addition, they will isolate mesenchymal (CD146+), endothelial (CD31+) and hemopoietic (CD45+) cell subpopulations. These samples will be prepared for sequencing by the Sethupathy lab (Dr. Lisa Kurtz and an MD/PhD Student, Mr. Timothy Dinh) and provided to core services at UNC or at commercial labs to generate the raw data for conventional RNA sequencing, small RNA sequencing, and methyl sequencing. The raw data will be analysed by Dr. Sethupathy and his associates with the help of a bioinformatics specialist, Dr. Wendy Pitman, and by Mr. Dinh. The findings from these studies will provide the control data that will guide us in analysing the fate of transplanted cells.

|M. Andrea Azcarate-Peril||Medicine, GI Division||Translational||Nofirstname.lastname@example.org||Modulation of the gut microbiome by probiotics and prebiotics||The overall goal of my research is to investigate the impact and mechanisms involved in the beneficial modulation of the gut microbiota by prebiotics (functional foods that stimulate growth of gut native beneficial bacteria) and probiotics (live bacteria that benefit their host). I specifically aim to develop prebiotic and probiotic interventions as alternatives to traditional treatments for microbiota-health related conditions, and to advance microbiota-based health surveillance methods.
Prebiotics are resistant to digestion in the upper gastrointestinal tract, arrive at the colon intact and increase the abundance of specific primary and secondary degraders with the final result of an expanded probiome, beneficial members of the intestinal microbiota. We have shown that pure prebiotics modulate gut microbiome composition and activity in humans and animal models increasing gut beneficial bacteria. In humans, the modulatory influence of pure galactooligosaccharides significantly improved clinical outcomes for lactose digestion and tolerance. Our current research investigate prebiotics as gut microbiome modulators of age-associated diseases to identify mechanisms of prebiosis in vulnerable populations.
Probiotics can reduce the risk of common infectious and acute diarrheal illnesses, and can be an alternative to treatments with antibiotics or anti-inflammatory drugs. Large-scale microbiome studies have established that most of the bacterial diversity contained in the gastrointestinal tract is represented at the strain level. Hence genomic and physiological characterization of isolates of probiotic potential is essential to determine unique attributes that will allow for personalized interventions. Our lab is conducting functional genomics studies to determine genetic components contributing to probiotic survival in the gastrointestinal tract and capability to metabolize prebiotics.

Studies with Latinas have underscored the importance of the family as a cultural value affecting recognition of the eating disorders as well as the centrality of the role of the family and its relationship to food and body image in Latino culture. My current work builds on my experience working with adults with bulimia nervosa in Puerto Rico which underscored the importance of incorporating the family early in treatment as a necessary cultural adaptation for Latinas. A second line of my research is to develop culturally sensitive psychoeducational materials that raise awareness and educate the Latino population about eating disorders. Considering that Latinos regularly delay treatment until symptoms are severe, tend to underutilize mental health services, and often terminate treatment prematurely, awareness and education could lead to early detection and be particularly helpful in reducing mental health care disparities. The development of fotonovela scripts (graphic novels) about eating disorders tailored for adolescent and adult Latinos will be used as a culturally sensitive way to raise awareness about these disorders in the Latino population.|

Comparison of sex steroids and gonadotropin levels (LH and FSH) in the normal population and individuals with sex chromosome abnormalities between the ages of 0 and 2 years. (Although it is known that sex steroid levels rise postnatally and the fall to prepubertal levels, normative values using a sensitive and specific assay (LC/MSMS) are not known. Because we are interested in the effect of sex steroid replacement on brain development, normative values and those in individuals with TS and other sex chromosome abnormalities must be known first.)

These anti-VEGF drugs will have been injected into their eye as treatment for the retinal edema which occurs during the healing phase following the onset of their retinal vein occlusion.
Anti-VEGF drugs work to decrease retinal edema. Oxygenation of the retina does the same thing. However, the concurrent effects of intravitreal anti-VEGF drugs on the oxygenation of the retina via the retinal circulation is currently unknown.
Using a non-invasive technique, called retinal oximetry, we will take (risk free)fundus photographs of the retina in these patients throughout the course of their treatment with anti-VEGF injections, and record changes in retinal oxygenation during this period.
We will determine the effect, either positive or negative, of injected anti-VEGF drugs on the normal oxygen supply to the retina during a course of treatment of a retinal vein occlusion using the current standard of care anti-VEGF injections.
|Maya Styner||Medicine||Translational||Yesemail@example.com||Exercise regulation of Bone and Metabolic Health||Our bones are not stagnant, rock-like things. They change. Marrow—the tissue inside bones—is full of various kinds of cells. And marrow is also full of fat. The amounts of these cells including the fat cells can decrease or increase over time .Bone marrow fat is known to be increased in clinical conditions of bone fragility, like osteoporosis. Our lab is interested in how exercise benefits health, specifically bone marrow health. Measuring the amount of fat in bone, in mouse models for instance, requires the use of small bone slices one at a time. These tedious methods have led to mixed results because bone slices don’t provide a clear picture of the entire amount of fat in bone. We collaborated with medical image analysis colleagues at UNC and developped quantitative means for quantifying bone fat. This rigorous quantification allowed us to learn a great deal about bone fat: it increases with high fat feeding, and it is significantly repressed by exercise. I am currently conducting experiments in caloric restriction, lipodystrophy and aged mice to understand the relationship between exercise, bone fat and bone formation. My background in Endocrinology and skeletal biology, combined with an interest in exercise physiology, make this an exciting venue for research into diet and exercise, which may be the most challenging issues facing the modern world.|

|Natasha Snider||Cell Biology & Physiologyemail@example.com||Liver Disease Mechanisms and Drug Targets||Dr. Sniderâ€™s lab studies the molecular basis of liver diseases and disorders linked to intermediate filament gene mutations. Her team uses biochemical, cell-based and in vivo approaches to identify potential disease targets and to understand their function and regulation. The major goal of Dr. Sniderâ€™s work is to promote the discovery of pharmacological agents that can slow or halt the progression of these diseases.
Liver disease development and progression are dictated by the individual and combined contributions of different genetic and environmental factors. Our previous work in mouse models linked liver injury susceptibility to the function of energy metabolism regulators, including the glycolytic enzyme GAPDH and the purine metabolizing enzymes nucleoside diphosphate kinase (NDPK) and ecto-5\'-nucleotidase CD73. Current efforts in the lab are aimed at understanding the regulation and cell-specific functions of CD73 in various stages of liver disease, including fibrosis, cirrhosis and hepatocellular carcinoma.
Intermediate filaments (IFs) are cytoskeletal structures that perform important mechanical and signaling functions. IF gene mutations are linked to a vast number of human pathologies, including skin fragility disorders, neuropathies, myopathies, liver diseases, metabolic dysfunctions, and premature aging syndromes. Effective treatments for diseases caused by IF gene mutations are lacking. Our long-term goal is to define the proteostasis network of IF proteins and to identify key features that are compromised by disease-causing or disease-promoting mutations. We are currently focused on various post-translational modifications (PTMs) and their cross-talk mechanisms.

Esophageal cancer is a highly lethal cancer, with less than 15% five-year survival, and its incidence is rapidly increasing. Patients who develop esophageal cancer often have a precursor condition, Barrett\\'s esophagus, also known as BE. Many people have BE - as many as 2-3 million Americans. If BE goes bad, it does so through a series of steps, called dysplasia. Our goal has been to identify those whose BE will progress to cancer, and to make an intervention to stop death from cancer.
Our center is one of several in the U.S. that have been dedicated to developing technologies to reverse the malignant degeneration in BE, while sparing the esophagus. We recently led a national consortium of centers in a sham-controlled, randomized trial of radiofrequency ablation, an endoscopic technology which destroys BE. This study, published in New England Journal of Medicine in May, 2009, demonstrated that subjects treated with the therapy had greater than 75% reversion to normal squamous epithelium, and a decrease in their risk of cancer of greater than 80%. We also are the lead U.S. center on a study of endoscopic cryotherapy using liquid nitrogen to ablate Barrett\\'s esophagus.
We are currently working on biomarkers, or early indicators, of progression to cancer in these patients.

|Nigel Mackman||Hematology & Oncologyfirstname.lastname@example.org||The role of tissue factor, coagulation, proteases, PARs and microparticles/microvesicles in hemostasis, thrombosis, and inflammation.||The focus of the Mackman laboratory is a protein called tissue factor (TF). This transmembrane receptor is the primary cellular activator of the coagulation protease cascades. TF is expressed constitutively on perivascular cells and initiates clot formation. After vascular injury, factor VIIa (FVIIa) binds TF and the complex initiates the clotting cascade by cleavage of FX to FXa and FIX to FIXa. Subsequent amplification of the clotting cascade by the intrinsic pathway produces large amounts of thrombin that cleave fibrinogen, activate FXIII and activate platelets. Tissue factor pathway inhibitor (TFPI) and activated protein C (APC) act to attenuate the clotting response. Coagulation and inflammation are linked through activation of protease-activated receptors (PARs). Activation of the clotting cascade leads to the generation of proteases that can cleave and activate PARs. PAR-1 is activated by thrombin and FXa, PAR-3 and PAR-4 are activated by thrombin, and PAR-2 is activated by FVIIa and FXa. This allows cross-talk between coagulation and inflammation.|

Formal care for persons with Alzheimer’s disease and related dementias is largely provided by NAs, who are >50% minority, 20% immigrant, 87% without a college degree, and often in poverty. NA well-being is critical to quality of care, but research aimed at improving NA well-being and care is hampered because existing measures translate poorly to the background and experience of most NAs.
To address this measurement gap, we will broaden the racial/ethnic and socioeconomic applicability of measures of NA well-being through four aims:
1) Conduct focus groups with diverse NAs and supervisors to determine the extent to which existing measures address constructs and use wording suitable to diverse groups.
2) Use the findings and best practices in measurement development to revise existing and develop new measures that are appropriate to NA diversity.
3) Conduct cognitive testing of resulting measures.
4) Pilot test the measures to assess psychometric properties.

|R. Jude Samulski||Pharmacologyfirstname.lastname@example.org||Gene Therapy||Dr. Samulski\'s research focuses on the study of the dependent parvovirus adeno-associated virus. AAV is the only known DNA animal virus which requires co-infection by a second unrelated virus in order to undergo productive infection. The DNA tumor viruses, adenovirus and herpes simplex virus provide the necessary helper functions for AAV. AAV not only utilizes gene products from these tumor viruses, but it interferes with their growth and with oncogenicity of cells transformed by these viruses. In the absence of a helper virus, AAV is able to integrate into host cell DNA and maintain a latent infection. Superinfection of these cells with a helper virus results in the rescue and replication of the AAV genome. The ability of AAV to integrate and maintain itself in host cells and subsequent rescue and replication of its viral sequences is of considerable interest. In some respects, this behavior is similar to phenomena observed with bacterial transposons, yeast movable genetic elements, Drosophila copia sequences, P elements, and the RNA tumor viruses. For this reason AAV has recently been described as a type of replicating transposon. Dr. Samulski has cloned the AAV genome into the bacterial plasmid pBR322 and demonstrated that this recombinant clone is infectious when introduced into human cells co-infected with a helper virus. This recombinant clone has provided a manipulatable system for the analysis of mechanism(s) involved in excision and integration of the adeno-associated virus genome. Based on these observations, he has been able to test AAV as a alternative viral vector for gene delivery. The ability to generate non-pathogenic viral vectors for current basic research have the long term potential of serving as reagents for use in clinical settings. He has established successful and long term gene expression over a year, which directly addresses the issue of molecular therapy required for genetic disorders. One of Dr. Samulski\'s current goals of research is to continue to derive delivery systems for use in gene therapy.|

This is felt to be potentially remediable by better educational and systems approaches to training and healthcare delivery.
Since 2013 we have been conducting a variety of educational interventions and clinical studies aimed at educating students, residents and faculty how to incorporate high value care practices into educational environments. Several projects around the overuse of telemetry, laboratory testing, and other technologies are ongoing. Educationally we have introduced HVC as an area of concentration in the TEC curriculum and other department specific resident education and faculty development.
Research as to the effects of these interventions both educational and clinical are ongoing but with room for expansion and new project development.

|Robert Aris||Pulmonary & Critical Care Medicinefirstname.lastname@example.org||Research Opportunities in Pulmonary Medicine: Pulmonary Hypertension, Cystic Fibrosis. and Lung Transplantation||Our group (3 faculty members, 2 research coordinators, and 1 fellow) is interested in research in Pulmonary Hypertension (PH), Cystic Fibrosis. and Lung Transplantation. We do research from basic to translational and to clinical. No real prior training is required. Projects are adjusted to meet the time frame available for research and the interest of the participating researcher. We have mentored >25 medical students over the past 15 yrs. One project is studying biomarkers (proinflammatory and procoagulant proteins among others) for PH from pulmonary arterial blood (obtained at the time of right heart catheterization) and comparing these markers to peripheral venous blood as well as blood from healthy controls (translational research). Another project looks at the effect of immunosuppressants on airway epithelial cells in vitro to better understand how inhaled immunosuppressants might work to prevent lung transplant rejection (basic/translational research). This project has multiple potential spin offs. Another series of projects is looking at improving bone healthy and systemic inflammation in Cystic Fibrosis (clinical and translational). In general we focus on innovative ways to use basic and translational research to improve health outcomes for people with complex lung diseases. Interested students are encouraged to participate in any/all aspects of our work or to design feasible studies that they can do mostly on their own with our assistance.|

Although there is some literature on metal detectors, there is very little on airport scanners and their ability to detect orthopaedic implants. Specifically, we would use de-identified patient information to establish the baseline demographics for the patient and we will analyze patient radiographs, BMI, side of implant, metallurgy, size of implant, and number of screws inserted. The time from surgery to travel will also be considered and a comparison will be made with the patient\'s experience in airport detection.|
|Ronald Falk||Nephrology & Hypertensionemail@example.com||ANCA Glomerulonephritis: From Molecules to Man||Glomerulonephritis and vasculitis caused by anti-neutrophil cytoplasmic autoantibodies (ANCA) is the most common form of rapidly progressive glomerular disease. To improve the lives of patients with ANCA disease, we aim to elucidate the underlying immunologic and pathogenic mechansisms and translate this knowledge into improved patient care. We are currently investigating epigenetic regulation of neutrophil genes and genes that modify the phenotype of ANCA disease. We are exploring the biology of relapse and remission in a unique cohort of patients from the perspective of epigenetic regulation of autoantigen genes, B cell autoreactivity and T cell dysregulation. Using animal models of ANCA disease, we are studying involvement of the alternative complement pathway and Fcy receptors in pathogenesis, induction of disease by different antigens, and the genetic basis for variations in disease severity. Providing translation of our more basic research into clinical invesigations to improve ANCA disease outcomes, we will use our discoveries about pathogenic roles for epigenetic regulation and complement activation by treating patients with retinoic acid to alter myeloid gene expression and with anti-C5 antibodies to block complement activation. As an extension of the discovery of anti-plasminogen antibodies, we will determine if venous thrombosis in ANCA disease patients is attributable to these antibodies. Through the Glomerular Disease Collaborative Network, we have followed patients with ANCA disease for almost a quarter century, obtaining crucial clinical and pathological information and biological specimens for our research studies. What we learn about ANCA disease pertains also to autoimmunity and inflammation in general.|

These patients undergo a variety of medical, behavioral, and surgical procedures for treatment of voice, swallowing, and airway disorders. Our research is focused on patient specific tailoring of treatment. In order to do this, we must be vigilant in our study of multidimensional outcome measures. These include analysis of patient reported outcomes (survey based), perceptual data (our grading of severity), objective data of voice from our voice lab, quality of life, depression/anxiety scores, general health outcomes, and anatomical data (trach dependency, aspiration scores, airway caliber) after various interventions.
In addition, as the associate residency program director and director of ENT curriculum for the medical school, we study a variety of teaching methods including simulation based teaching, effect of Epic on training, how to pick the right applicant, and more.
We have a variety of projects that can be completed in the allotted time in the above categories.
|Ryan Miller||Pathology & Laboratory Medicineemail@example.com||Targeting the glioma kinome for personalized diagnosis and therapy||Dr. Miller is an Associate Professor in the Departments of Pathology & Laboratory Medicine and Neurology whose research and clinical efforts are focused on primary brain tumors, particularly gliomas. His work has established that the genomic landscape of human gliomas consists of multiple molecular subtypes with distinct genomic profiles and therapeutic responses. However, the paucity of models that faithfully recapitulate its genomic heterogeneity has prevented this knowledge from significantly impacting patient management. His laboratory is one of the few nation-wide that has developed both conditional, inducible and non-germline genetically-engineered mouse models to investigate the pathogenetic role of glioma mutations and the cellular lineages in which they occur. His lab utilizes these models, comparative genomics, proteomics and drug profiling, to develop novel combination therapies to combat resistance to single agent kinase inhibitors. His work will aid development of new strategies to personalize the diagnosis and treatment of gliomas.|

|Sam Lai||Microbiology & Immunologyemail@example.com||Immune protection based on interactions between IgG-Fc and mucins||Most infections transmit at mucosal surfaces, and our immune system secretes more antibodies into mucus than either the blood or the lymph. My lab uses various tools from biophysics and molecular biology to elucidate immune defense mechanisms at the mucosa. Specifically, we are discovered a novel mechanism of antibody protection at mucosal surfaces: trapping individual pathogens in mucus. Ongoing studies include quantifying the potency of this protective mechanism, the biochemistry governing antibody-mucin interactions, quantifying protection against both viral and bacterial pathogens in human secretions and different animal models across various mucosal secretions, and screening antibodies that may provide more effective protection. We welcome students with a keen interest in methods that improve protection against infectious diseases at mucosal surfaces for a short, 3-month research experience in our lab. The students will gain exposure to techniques in biophysics (high resolution fluorescence microscopy), Luminex multiplex ELISA, molecular biology, viral/bacterial cell cultures, animal studies, and studies with human specimens. Examples of our work in this area can be found at http://www.nature.com/mi/journal/v7/n5/full/mi2013120a.html and http://mbio.asm.org/content/6/5/e01084-15.

|Sam Weir||Family Medicinefirstname.lastname@example.org||Improving Clinical Efficiency in Outpatient Primary Care Practice||This project will be a follow on to a project to improve clinical efficiency done by Matt Oettinger, a third year resident in Family Medicine. Mattâ€™s project, to be completed in April and May of 2013, includes:
1. Researching the literature on clinical efficiency in primary care, including patient flow in different clinical models;
2. Reviewing and analyzing data from the FMC clinical flow efficiency study;
3. Continuing to improve personal clinical efficiency skills in day to day clinical practice
4. Testing specific improvements suggested from literature search in both personal and team PDSA mini-projects
5. Producing a scholarly work (short paper or poster) demonstrating efficiency/flow lessons learned, and
produce to the FMC R&R committee for further augmentation of practice redesign process
The summer research project would be to develop, implement, and evaluate a spread strategy so that the improvements in clinical efficiency learned by Matt become available to other FMC faculty and residents who see patients in the FMC. Resources on spread strategies from the Institute for Healthcare Improvement will be utilized to structure the work. The hope would be to submit this work as a poster for presentation at a national meeting.
|Samantha Meltzer-Brody||Psychiatryemail@example.com||Epidemiological and Biological Predictors of Postpartum Depression||My research is focused on understanding the epidemiological and biological risk factors and underlying mechanisms of postpartum mood disorders (PMD). PMDs are the most common complication of childbirth and cause significant morbidity and mortality. Postpartum depression (PPD) has a prevalence of 10-15% and is the most frequent type of PMD. Postpartum psychosis (PP) is a rare but severe form of PMD that can result in tragic consequences including suicide and infanticide. The relationship between PPD and PP is uncertain, as is their relationship to major depressive disorder (MDD) and bipolar disorder (BIP). We currently have a poor understanding of who will develop PPD or PP, and whether and how the two disorders are related. Research focused on this line of inquiry could provide new knowledge crucial to understanding the risk factors and course of PMD that could eventually also prove to be key to understanding the etiology of mood disorders outside the perinatal period. This new knowledge will be significant because it will define the epidemiological and mechanistic predictors and course of PMD, thereby identifying a potentially modifiable risk factor for PPD and PP. Ultimately, this work will support strategies to identify women at risk and implement interventions to prevent PPD and PP and their adverse sequelae for mother and child.|

|Saskia Neher||Biochemistry & Biophysiologyfirstname.lastname@example.org||Regulation of Lipoprotein Lipase Activity||My lab studies multiple aspects of lipase regulation. Mammalian lipoprotein lipase (LPL) plays a critical and complex role in lipid metabolism. In humans, deficient levels of LPL can cause hypertriglyceridemia and associated disorders, such as diabetes and atherosclerosis. LPL cannot efficiently exit the ER and achieve appropriate levels without a transmembrane protein whose identity was only recently discovered, lipase maturation factor (LMF1). In cells lacking LMF1, inactive LPL is retained in the ER as large eaggregates that are subject to degradation. We use biochemistry and cell biology to study how LMF1 promotes LPL exit from the ER. Once secreted into the blood, LPL activity is also regulated. LPL activity is inhibited by a protein known as ANGPTL4, which is induced in adipose tissue in response to fasting. We study the mechanism of ANGPTL4 inhibition of LPL.|

|Scott Magness||Gastroenterology & Hepatologyemail@example.com||Intestinal Stem Cells||The primary focus of my research is to understand the genetic mechanisms underlying stem cell maintenance and differentiation with the goal of translating this information into therapeutic strategies. We have identified that distinct levels of the transcription factor, Sox9, differentially mark stem cells and progenitor cells in the small intestine epithelium. Using a novel Sox9EGFP mouse model, cell surface markers, and FACSorting we are able to specifically enrich for single multipotent intestinal epithelial stem cells that are able to generate â€˜mini-gutsâ€™ in a culture system. Our studies are now focused on manipulating, in vitro, the genetics of stem cell behavior through viral gene therapeutics and pharmacologic agents. Additionally, we are developing stem cell transplantation and tissue engineering strategies as therapies for inborn genetic disorders as well as damage and disease of the intestine. A new area of research focus is on cancer stem cells. Using novel animal models and tissue microarrays from human colon cancers, we are investigating the role of Sox9 in colorectal cancer and assessing Sox9 expression patterns as a predictor of outcomes.|
|Sean McLean||Surgeryfirstname.lastname@example.org||Basic Mechanisms of pulmonary hypertension in Congenital Diaphragmatic Hernia.||Pulmonary hypertension in patients with congenital diaphragmatic hernia is highly lethal. Presently no definitive treatment exists for pulmonary hypertension in CDH and other forms because the pathogenic mechanisms are complex and not understood. Pulmonary vascular remodeling is the central cause of pulmonary hypertension, and smooth muscle cells drive this process. Our laboratory investigates smooth muscle cell related mechanisms in the development of pulmonary hypertension. Specifically we focus upon the protein Slit-3 as a mediator of smooth muscle cell differentiation and migration in the development of the pulmonary circulation. We believe alterations in Slit-3 signaling contribute to alterations in smooth muscle cell function and phenotype that lead to the development of pulmonary hypertension. In our laboratory, we work with a mouse model for congenital diaphragmatic hernia, Slit-3 null mouse, to investigate the mechanisms related to pulmonary vascular remodeling in the context of congenital diaphragmatic hernia. In our laboratory, we use advanced cell and molecular biology techniques and small animal physiology techniques in our investigative efforts. Students in thhe laboratory will have the opportunity to become engaged in a basic science laboratory exploring a clinical problem that presently has no answers. Please contact Dr. McLean for questions related to the laboratory or other areas related to surgical-science.|
|Seema Garg||Ophthalmologyemail@example.com||Retinal imaging, diabetic retinopathy telemedical screening, ophthalmic genetics||I have been interested in the applications of technology in medicine for many years. I have piloted the diabetic retinopathy (DR) telemedicine program at UNC in which we have increased DR screening rates from 30% to 70%. I am also interested in novel retinal imaging modalities. I am currently supervising research with a novel imaging device called the retinal oximeter. It is a non-invasive method based on a traditional fundus camera, to measure retinal oxygen saturation in retinal vessels based on the differential light absorbency of oxygenated and deoxygenated hemoglobin. At UNC, our research group has produced a normative database of retinal oximetry, studied the repeatability of the instrument and has evaluated this technology in a variety of disease states such as diabetic retinopathy and radiation retinopathy. Diabetic retinopathy is a potentially blinding microvascular disease characterized by progressive retinal ischemia. Our research group is studying the relationship of retinal oximetry and fluorescein angiography in order to characterize the retinal oxygenation status in various stages of diabetic retinopathy. If we can determine a non-invasive marker for pre-clinical diabetic retinopathy such as decreased retinal oxygenation, retinal oximetry may potentially serve as a screening device for patients who are at higher risk for retinopathy. I am also interested in hereditary eye disease. Nearly half of the patients in our ophthalmology/genetics clinic have negative clinical genetic testing. Our goal is to employ emerging genetic technologies such as next-generation whole-exome sequencing to determine a molecular diagnosis for these patients.|

|Silvia Ramos||Obstetrics & Gynecologyemail@example.com||Female Infertility||I have developed a unique mouse model of female sterility that may represent a significant proportion of unexplained infertility seen in women. The DeltaN-Zfp36l2 mouse model is linked to the disruption of the earliest stages of embryogenesis the only one of its kind demonstrating the involvement of an mRNA destabilizing protein in the progression of the embryo beyond the two-cell stage (Ramos et al, Development 2004). Zinc Finger Protein 36 Like 2, ZFP36L2, belongs to the TTP (ZFP36) family of proteins that destabilize certain mRNA containing ARE elements. Although TTP has been involved in modulation of inflammatory and autoimmune responses; ZFP36L2, which is ubiquitously expressed, affects only the earliest stages of embryogenesis (Ramos et al, 2004) and hematopoiesis (Stumpo et al, 2009). Therefore it is my goal to investigate the mechanism which ZFP36L2 leads to female infertility. This basic research will lead to molecular insights on this important condition for which no direct diagnosis method is currently available.|

|Stergios Moschos||Hematology & Oncologyfirstname.lastname@example.org||Understanding the Biology of Melanoma Brain Metastases||Over the last 2 years my research focus has been to study the biology of melanoma brain metastases, in hopes to understand why melanoma is the cancer that most frequently goes to the brain, why it has the highest propensity to bleed, and why its prognosis is poor in general. The long term focus is to develop rational therapies for this disease site group, the incidence of which will exponentially rise over the next few years given the advent of new effective, recently F.D.A-approved therapies for metastatic melanoma (e.g. vemurafenib, ipilimumab).
As part of this effort, and during the last 2 years of my tenure as an Assistant Professor at the University of Pittsburgh SPORE-funded Melanoma program I established a tissue database that consists of 101 formalin-fixed paraffin-embedded tumor blocks obtained from patients who underwent craniotomy for melanoma brain metastases. Following detailed histopathologic, whole genome expression, and immunohistochemical analysis, we identified that high immune infiltrate, low intratumoral hemorrhage, and high melanin are associated with prolonge survival. In addition, genes involved in Notch, Wnt, HIF1alpha, G-protein coupled receptor, and Tubby signaling are associated with worse prognosis.
My plan is to validate these findings in the UNC-CH melanoma brain metastases cohort and in addition perform whole genome exon sequencing on brain melanoma metastases, extracranial metastases, and primary melanoma from the same patients to identify metastasis-specific genes that are distinct from ones that have already described (B-Raf, N-Ras).

|Temitope Keku||Gastroenterology & Hepatologyfirstname.lastname@example.org||Translational studies of colorectal cancer||My research involves translational research combining basic science with epidemiology to gain a better understanding of the etiology and pathogenesis of colorectal cancer. My research interests are: genetic and molecular epidemiology of colorectal cancer; assessment of the contribution of genetic and lifestyle/dietary factors to colorectal cancer susceptibility; identification of germ-line or tumor characteristics associated with cancer risk and clinical outcomes; identification of novel biomarkers for early detection to define risk groups for prevention; cancer health disparities; defining the role of gut microbiome in etiology of colorectal cancer. Current studies are focused on evaluating the gut microbiome and interactions between microbiome, diet, and inflammation in relation to colorectal adenomas and cancer. Our findings suggest that there is a microbial signature associated with colorectal adenomas. This finding has potential clinical impact that could lead to development of novel strategies to manipulate the gut microbiota in order to prevent colorectal adenomas and cancer.
There are opportunities to plan associated projects depending upon individual interests and experience. Summer students will have the opportunity to participate in ongoing microbiome studies and be involved in high throughput analysis of the microbiome and correlations with diet, inflammation and adenomas. Existing datasets from previous studies are also available for students who wish to look at other aspects of colorectal cancer etiology.

We are also studying EVLP of human lungs. IRI is mediated by toll-like receptors (TLRs) of the innate immune system. IRI is associated with early edema in the lung and activation of a variety of inflammatory signaling pathways, including NF-kb and MAP kinases. Projects suitable for short term research include performing cell culture experiments of simulated IRI and looking at the effects of pathway inhibitors or other potential therapies. Other molecular biology techniques we use are protein and RNA extraction, Western blots to identify proteins, RT-PCR, and immunohistochemistry. Because our research explores mechanisms and identifies potential therapies that can be introduced clinically, it is very translational.|

My research focuses on understanding the impact obesity has on ovarian and endometrial cancer development and progression which may invariably dictate different risk reduction strategies and treatment options for this particularly high-risk patient population. We hypothesize that obesity gives rise to biologically and metabolically different cancers than those that arise in a non-obese environment; and thus, obesity-driven cancers may have unique vulnerabilities that could be targeted for treatment. In this pursuit, I have investigated many novel targeted therapies for the treatment of obesity-driven ovarian and endometrial cancer, including mTOR inhibitors, arsenic, a human monoclonal antibody to the insulin growth factor-1 receptor (IGF-1R), soy, genistein, cox-2 inhibitors, statins and metformin. My pre-clinical work has led to several investigator-initiated clinical trials, including pre-operative window studies of metformin and atorvastatin in obese endometrial cancer patients, a pilot study of meformin for the treatment of endometrial hyperplasia, a phase II trial of metformin in combination with the levonorgestrel-intrauterine device in endometrial hyperplasia/cancer patients, a phase II trial of metformin (plus paclitaxel/carboplatin) in newly diagnosed ovarian cancer patients and a randomized phase II/III evaluation of paclitaxel/carboplatin/metformin versus paclitaxel/carboplatin/placebo in advanced and recurrent endometrial cancer patients.|

|William Kim||Hematology & Oncologyemail@example.com||Genetics of Bladder and Kidney Cancer||The Kim Lab is focused on understanding the genetic and epigenetic events involved in the initiation and progression of renal cell carcinoma (RCC) and bladder cancer. Through NextGeneration sequencing of primary human tumors and the use of genetically engineered mouse models (GEMMs), as well as in vitro systems, our goal is to identify the critical genomic and epigenetic changes that are drivers of RCC and bladder cancer. Our ultimate goal is to elucidate the functional consequences of these genomic events in order to pinpoint novel, high impact therapeutic targets for therapy.

Providing care to these patients is a priority of the NIDDK.
Aims: This survey will attempt to answer the following questions:
1. How do people with ABL cope? Preliminary data suggests some maladaptive ways of coping such as not eating before going out.
2. Does severity of ABL and its impact on quality of life influence how people cope with ABL?
3. Does coping style influence whether people consult for ABL?
Methods: An internet survey will collect data from approximately 200 people with ABL. This database will be completed before May 2016. Medical student will be mentored in analyzing the data, preparing an abstract for submission to the annual meeting of the Am Gastroenterol Assoc, and preparing a manuscript for publication in a journal.
|Yueh Lee||Radiology||Translational||Nofirstname.lastname@example.org||Translational||My areas of research interest are focused on translational medical imaging - bringing techniques developed by myself or in research labs on campus into clinical applications.
I work with two major imaging modalities for a number of clinical applications:
First, I work extensively with the carbon nanotube x-ray source invented on campus. Our current applications include breast, cardiac and chest tomosynthesis.
We have extended this work into novel radiation therapy approaches.
Second, I work extensively with F19 (non-radioactive) based MR imaging for Cystic fibrosis (human) and cell tracking (pre-clinical). We also have a few novel F19 applications that are in development.

|David Friedlander||Urology||Clinical||Yesemail@example.com||Health services research, comparative effectiveness, surgical outcomes, disparities in care||Recognizing the significant cost posed by inefficient or “low-value” health practices, significant effort has been put into advancing value-based purchasing reforms. Public and private insurers have developed a particular interest in identifying modifiable sources of clinical variation that may contribute to inefficient care. Research conducted during both my residency and fellowship years have directly
contributed to the growing body of literature aimed at identifying the aforementioned sources of clinical variation. More importantly, my recent work has looked at non-clinical drivers of care variation, which to date has been largely overlooked. More specifically, collaborators and I have demonstrated the important role that socioeconomic factors play in determining the quality of care received by individuals undergoing surgery. Similarly, this work has helped to reframe how surgical quality should be defined, and in doing so aims to identify individuals at risk of experiencing low-value care. These findings coupled with the proposed research project ultimately seek to develop strategies aimed at steering at-risk individuals away from low value pathways of surgical care, and in doing so both improve the patient experience and lower health care spending.

|Nancie Archin||Infectious Disease||Translational||Yesemail@example.com||HIV latency||Persistent, latent HIV infection despite anti-retroviral therapy (ART) remains a formidable barrier towards achieving an HIV cure. A major approach to target persistent HIV infection involves latency reversal, using small molecules capable of inducing expression of the HIV provirus, followed by immune mediated clearance of infected cells. The successful implementation of this or indeed any other approach to HIV eradication will require specific knowledge about the nature of the reservoir and the interplay of factors regulating the reservoir in all human populations. Women constitute one half of people living with HIV disease yet, they represent a minority in HIV cure studies. Our laboratory uses molecular biology and biochemical methods to 1) define sex-specific and other factors that contribute to HIV persistence in people living with HIV with a particular focus on women, 2) define modalities to disrupt latency and clear latently infected cells, and 3) apply these observations in clinical applications.|
