Dr. Sahni is an Associate Professor of Medicine at Harvard Medical School and an Associate Scientist at the Hinda and Arthur Marcus Institute for Aging Research at Hebrew SeniorLife. She directs the Nutrition Program at the Marcus Institute and co-directs the Musculoskeletal Research Center.

Dr. Sahni is a Nutritional Epidemiologist with expertise in determining the role of nutritional factors on chronic diseases of aging such as osteoporosis, sarcopenia, frailty, and consequent declines in physical function. Since diet is a modifiable risk factor, her research work has a direct impact on the prevention of these musculoskeletal diseases and their consequences among older adults. Dr. Sahni received her M.S. and Ph.D. degree in Nutritional Epidemiology from Tufts University, Boston, MA. She also holds a Master’s degree in Dietetics from Delhi University, India. She completed her post-doctoral fellowship in geriatrics and musculoskeletal epidemiology from the Institute for Aging Research, Hebrew SeniorLife, and Harvard Medical School.

Dr. Sahni also devotes time to teaching nutrition and epidemiology courses both at Harvard Medical School and at Harvard T. H. Chan School of Public Health. She mentors graduate students, post-doctoral fellows, and dietetics interns. She organizes the Quarterly Nutrition Seminar Series at the Marcus Institute for clinicians, dietitians, and researchers. Dr. Sahni has held several leadership positions with the American Society for Nutrition (ASN) and the American Society for Bone and Mineral Research (ASBMR). She has previously served as the chair of the American Society of Nutrition’s (ASN) Nutritional Epidemiology Research Interest Section. She has also served on the editorial boards of the British Journal of Nutrition, Journal of Nutritional Sciences, and the Nutrition Journal and was honored as an Excellence in Nutrition Fellow of the American Society for Nutrition.
