Emily Oken, MD, MPH
Dr. Oken is an Associate Professor in the Department of Population Medicine. Her research is focused on the health effects of nutrition and environmental toxicants on health and disease, with a particular focus on pregnancy early childhood. She has studied the balance of risk and benefit from maternal fish consumption during pregnancy on child development, long term health effects of breastfeeding for both mother and child, and determinants and sequelae of excess gestational weight gain. She has also performed a number of studies on the influence of modifiable behaviors during pregnancy, such as smoking, physical activity, and diet, on risk for obesity among both mothers and their children. Within the Department of Population Medicine Dr. Oken is Director of Faculty Development and site director for the Harvard General Medicine fellowship. At Harvard Medical School, she is a Peabody Society Research Fellow, in which role she guides medical students in meeting their research requirement for graduation. Dr. Oken completed residency training in both internal medicine and pediatrics. She practices as a primary care physician at the Fish Center for Women's Health at Brigham and Women's Hospital, and has a clinical interest in medical care for women before, during, and after pregnancy.
