Josiemer Mattei

Dr. Mattei is the Donald and Sue Pritzker Associate Professor of Nutrition at the Department of Nutrition, Harvard T.H. Chan School of Public Health. She investigates the genetic, dietary, and psychosocial risk factors of obesity, type 2 diabetes, cardiovascular disease, and allostatic load in racial and ethnic groups as well as underserved and minority populations, as a framework to explain health disparities. Her emphasis is on Hispanics/Latinos in the U.S. and Latin America. Her multiple projects include longitudinal cohort studies in Puerto Rico, mixed-methods projects on diet, stress, and weight stigma, collaborations with epidemiological cohorts of Hispanics/Latinos in the Unites States, and culturally-tailored dietary interventions to prevent type 2 diabetes and heart disease in Boston and Puerto Rico. Her work extends to several Latin American countries through collaborative partnerships. Dr. Mattei promotes evidence-based policy and programs for chronic disease prevention in Puerto Rico and US-Latino communities. Her ultimate goal is to help Latinos and other ethnic and minority populations eat healthy and be healthy.
