My research focuses on developing dietary and lifestyle strategies to prevent and manage diabetes and its complications and investigating earlier life risk factors for diabetes and cardiovascular disease over the life-course. 


I am an Assistant Professor, the Department of Epidemiology, Tulane University School of Public Health and Tropical Medicine. I have completed my doctoral study in maternal and infant nutrition and clinical epidemiology at University Toronto and postdoctoral training in classical epidemiologic methods at Harvard T.H. Chan School of Public Health working with large-scale cohort studies. I currently lead a research project on cardiometabolic life-course trajectories in children and adults.
