I am a nutritional epidemiologist, and my research focuses on dietary and lifestyle predictors of cardiometabolic diseases. I am particularly interested in examining these associations in groups with high cardiometabolic burden such as Hispanics and South Asians. My research group also utilizes -omic technologies, including metabolomics and proteomics, to examine diet-disease mechanisms and to identify dietary biomarkers. I am the PI of several NIH R01 grants that aim to identify dietary biomarkers and mechanistic pathways using omic technologies. Globally, my research has focused primarily in India where there is a rapid nutrition transition that is underway. We recently completed a Bill and Melinda Gates foundation grant to examine diet quality indicators in low- and middle-income countries and a community intervention study to examine the effect of diet and lifestyle changes on non-communicable diseases in Bathinda, Punjab. Through a recently funded USDA grant, we are conducting a randomized controlled trial to examine the effect of peanut consumption on cardiometabolic risk among overweight and obese Asian Indians. In addition to my research, I serve as the course director for two graduate nutrition courses (NUT 200 and ID 276) at Harvard T.H. Chan School of Public Health and co-lead a graduate course in Public Health Nutrition (NUT 201).
