She investigates genetic, dietary, and psychosocial determinants of cardiometabolic diseases and allostatic load in racial/ethnic groups and underserved populations, as a framework to explain health disparities. 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. Her productive body of work was recognized with the Mark Bieber Award for Outstanding Nutrition-related Research by the American Heart Association, of which she is a Fellow. She is also a Robert Wood Johnson Foundation Culture of Health Leader guiding program and policy changes for healthy eating in Latino communities. Dr. Mattei works diligently towards the inclusion and advancement of under-represented groups in research studies, of minority students in higher education, and of women and minorities in science and academia.
