My research focuses on developing strategies to prevent and manage chronic diseases 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 at Harvard T.H. Chan School of Public Health working with large-scale cohort studies using classical epidemiologic methods. I currently lead NIH and NSF funded research projects, on life-course and omics approaches to chronic disease prevention and on COVID-19 and maternal and infant health.
