Her emphasis is on Hispanics/Latinos in the U.S. and Latin America. Dr. Mattei combines epidemiological research with culturally-tailored community interventions, including collaborations with large cohorts of Hispanics/Latinos as well as new observational and intervention studies in Puerto Rico and in Boston, funded by multiple awards from the National Institutes of Health and private foundations. Her work extends to several countries, especially in Latin America, through a global collaborative partnership. Her ultimate goal is to help Latinos and minority and underserved populations eat healthier and be healthy.
