Dr. Okereke is a Board-certified geriatric psychiatrist and Associate Professor of Psychiatry and Associate Professor of Epidemiology at Harvard Medical School and the Harvard T. H. Chan School of Public Health. She is Director of Geriatric Psychiatry and Research Director of the Geriatric Psychiatry Clinical and Research Program at Massachusetts General Hospital. Dr. Okereke’s programmatic goals are: (1) to identify modifiable risk factors involved in adverse mental aging and (2) to translate and apply knowledge gained into strategies for large-scale prevention of late-life depression and cognitive decline. Her research portfolio has been supported by numerous National Institutes of Health, University and foundation awards. Currently, she is: evaluating the role of dietary factors, such as vitamin D and omega-3, along with novel biologic markers in relation to risk of late-life cognitive decline and depression; testing effects of nutritional interventions on late-life mood in large-scale randomized trial settings; and addressing relations of later-life depression and anxiety to molecular markers of biological aging, with attention to their potential contributions to disparities in health and aging.
