Autism Spectrum Disorders (AUT) back_to_top_icon.JPG

chair_mark_daly.jpgMark Daly, PhDis the founding chief of the Analytic and Translational Genetics Unit (ATGU) at Massachusetts General Hospital and an assistant professor in the Harvard Medical School.  His research has historically focused on the development and application of statistical methods for the discovery and interpretation of genetic variation responsible for complex human disease and with the creation of the ATGU, he and other core faculty are focused on the interpretation of genome sequence and the use of genome information in clinical settings.  Mark is also a senior associate member and co-director of the Program in Medical and Population Genetics at the Broad Institute, where he leads many large scale genome sequencing studies in autism and inflammatory bowel disease.

Daly’s group has developed numerous methods and widely used software tools, including GENEHUNTER and HAPLOVIEW, genetic analysis tools used in thousands of laboratories worldwide; GRAIL and DAPPLE, web-based utilities for the interpretation of genome-wide association results; and have contributed to additional widely distributed tools developed in the Broad community such as PLINK and GATK.  His earlier work at the Whitehead Institute and Whitehead/MIT Center for Genome Research (precursor to the Broad Institute) was instrumental in developing an understanding of patterns of variation in the human and mouse genomes, and in the use of these patterns in disease gene mapping.

While developing computational and statistical methods that can be broadly applied, his group has several primary medical genetics research foci.  He has extensive research program in neuropsychiatric genetics - particularly in autism, schizophrenia and ADHD – and has led large-scale GWAS and exome sequencing efforts in this area.  His lab serves as the analytic hub for the Psychiatric GWAS Consortium, and international consortium leading the largest collaborative GWAS studies in 5 major psychiatric disorders.  He also has a longstanding effort in the mapping of genes for Crohn’s disease and ulcerative colitis where he helped found and lead an international effort that has identified more than 150 genetic risk factors and, in collaboration with Dr. Ramnik Xavier’s group, pursues the functional interpretation and clinical ramifications of these continued gene discovery efforts.

More recently, the group also participates in numerous studies using exome sequencing to articulate the genetic origins of rare inherited diseases, early-onset and pediatric cancers, and severe adverse drug responses. He is also a visiting professor at the Finnish Institute of Molecular Medicine (FIMM) in Helsinki and has co-authored more than 50 manuscripts with Finnish scientists studying the genetic origins of human disease.

Mark received his B.S. in physics from MIT and his Ph.D. in human genetics from Leiden University, Netherlands. Mark is a recipient of the 2014 Curt Stern Award, presented by the American Society of Human Genetics for outstanding scientific achievements in human genetics.  He has an extensive publication record with an h-index of 150 and has been listed multiple times by publisher Thomson-Reuters as one of the top 10 most cited scientific authors.

Chan School of Public Health (Harvard-Chan) and leads the Global Neuropsychiatric Genomics Initiative of the Stanley Center for Psychiatric Research at Broad Institute. The broad goal of this initiative is to advance the genetic analysis of serious mental illness while contributing to global mental health equity by expanding the infrastructure and research findings from large-scale psychiatric genetic epidemiology to Africa and Mexico. 

At Harvard-Chan Koenen does research and teaches about trauma and post traumatic stress disorder (PTSD). Her work on PTSD focuses on three areas. First, she studies why, when exposed to a similar traumatic event, some persons develop PTSD while others are resilient. She is particularly interested in how genes shape risk for PTSD. Much of this work is done through the PTSD working group of the Psychiatric Genomics Consortium that she co-leads with Kerry Ressler and Israel Liberzon. Second, she investigates how trauma and PTSD influence weight gain and alter long-term physical health. Third, she documents global burden of trauma and PTSD through her work with the World Mental Health Surveys. Koenen also co-leads the training program in psychiatric epidemiology and biostatistics. Koenen’s work also uses research findings to advocate for evidence-based prevention of PTSD and response to trauma survivors, particularly victims of sexual violence.

In May 2011, Dr. Koenen testified before the House Foreign Affairs Full Committee hearing “Peace Corps at 50,” about the epidemic of sexual violence and victim blaming culture of the Peace Corps. She has written for the Boston Globe, the Washington Post, the Huffington Post, and the Women’s Media Center’s Women Under Siege Project, a journalism project founded by Gloria Steinem that investigates how rape and other forms of sexualized violence are used as tools in conflict.
