Her laboratory is broadly interested in how changes in nutritional status (undernutrition or obesity) and nutritionally regulated hormones, such as leptin and insulin-like growth factor-1, influence T cell immunity and immunometabolism in the context of infection, autoimmunity, and cancer. Her research has been supported in large part by competitive awards from the National Institutes of Health and from foundations and societies including The Hartwell Foundation, the Pediatric Endocrine Society, the American Association of Immunologists, and the National Multiple Sclerosis Society. Overall, her academic contributions have been recognized in a number of ways, including publications in top-tier peer review journals, local, national and international presentations, and several awards. Clinically, Dr. MacIver sees children, adolescents, and young adults with all types of endocrine disorders, including disorders of growth, puberty, and hormones, as well as children with diabetes mellitus. She also has a strong commitment to teaching and mentoring trainees in both the clinical and laboratory setting, which she has demonstrated by training numerous residents, fellows, graduate students, and post-doctoral fellows through the years in multiple settings.

Ali S. Calikoglu, MD Professor of Pediatric Endocrinology	Ali Calikoglu, M.D Division of Pediatric Endocrinology and Diabetes Professor of Pediatrics Find-a-Doctor profile
In 1982, he received his doctorate in medicine from Ankara University in Turkey. He completed his residency in pediatrics at Hacettepe University, Ankara, Turkey. He then served as instructor in pediatrics at Hacettepe University. Upon arrival in the United States, he pursued a fellowship in pediatric endocrinology in the Department of Pediatrics at UNC, Chapel Hill. Since he finished his fellowship, he has been a faculty at the same institute. He served as Division Chief between 2008 and 2013. Dr. Calikoglu has been honored with the Turkish Physicians Foundation Award, the Clinical Investigator Award from the National Institutes of Health/National Institute of Diabetes and Digestive and Kidney Diseases. He is a member of the Society for Pediatric Research, Pediatric Endocrine Society, and Endocrine Society. He has published over 70 peer-reviewed articles, books and book chapters in his areas of interest, namely regulation of IGF-I system proteins in developing mammalian brain, vitamin deficiency and growth disorders in pediatric endocrinology and pediatric/adolescent diabetes. He is co-leading the effort to develop a specialized, multi-disciplinary clinic for patients with Differences of Sex Differentiation (DSD). This group includes specialists from Pediatric endocrinologists, pediatric urologists, pediatric surgeons, child psychiatrists and psychologists, neonatologists, general pediatricians and ethicists. The group has developed a management protocol for best practice guidelines for UNC and established the multi-disciplinary clinic. This clinic is the only such a clinic in NC and surrounding states, and fulfills a great need for comprehensive and multidisciplinary management of individuals with DSD. He has involved in both investigator-initiated studies and multi-center clinical trials that are funded by NIH, non-profit foundations (i.e. JDRF) and industry. The investigator initiated studies have primarily focused on pediatric diabetes. In collaboration with a diabetes center in Turkey, he has demonstrated that the symptom spectrum of hypoglycemia extends beyond adrenergic and neuroglycopenic symptoms and includes behavioral and psychosensorial symptoms. In another study, he showed that diabetic ketoacidosis acutely leads to a special spatial memory defect, which may be contributing to the long-term cognitive deficits observed in patients with diabetes mellitus. The second arm of study that investigates potential affected pathways in CNS is currently ongoing. He is the principal investigator of TrialNet at UNC which is an NIH-supported multicenter trial exploring natural history of diabetes and testing new strategies that would prevent or delay the progression of diabetes in high-risk populations. Similarly, he has involved in clinical trial from another NIH-supported multi-center group, Type 1 diabetes EXCHANGE. He has participated several industry-sponsored clinical trials on pediatric GH deficiency, Growth hormone insensitivity syndrome and pediatric type 1 diabetes. He has worked with fellows in diagnosing and defining the gene mutations causing rare diseases including thiamine responsive megaloblastic anemia syndrome, delayed puberty caused by a mutation in the gene encoding FSH beta chain, familial hypocalciuric hypercalcemia, Schwachman-Diamond syndrome, Hb-Raleigh and vitamin D dependent rickets type 1.
