Joshua Petimar

Lecturer

Joshua Petimar, ScD is a Lecturer within the Department of Population Medicine at the Harvard Pilgrim Health Care Institute and Harvard Medical School. His work is focused on the effects of public health nutrition policies on diet quality. His current work primarily uses sales data from food retailers and longitudinal data from large cohort studies to investigate research questions related to calorie labeling, nutrition assistance programs, and the effects of the food environment on diet and health. He pursues answers to these policy-relevant questions using natural experiments and epidemiologic methods for causal inference. He received his joint doctorate in Nutrition and Epidemiology from the Harvard T.H. Chan School of Public Health, where he previously studied relationships between diet, obesity, and cancer.
