During her predoctoral studies, she was a fellow in Reproductive, Perinatal, and Pediatric Epidemiology where she studied genetic and epigenetic risk factors for a variety of outcomes and became interested in the developmental origins of health and disease. Dr. Moore’s research interests include genetic epidemiology, epigenetics, and the developmental origins of chronic diseases. Under the direction of Sonja Berndt, Pharm.D., Ph.D., investigator, OEEB, Dr. Moore examines genetic risk factors for prostate cancer, non-Hodgkin lymphoma, and obesity, including the role of mitochondrial DNA copy number in prostate cancer risk in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Screening Trial.
