Personal profile

Research Interests

My work aims to eliminate health disparities in U.S. Latinos by examining the underlying causes and developing interventions to address them. Since 2007, my colleagues and I have focused on community health workers as a culturally-competent workforce to promote health and prevent disease in this population. Partnered closely with community-based organizations, we have developed and tested community health worker programs to prevent cancer, cardiovascular disease, and most recently diabetes. We conduct qualitative and epidemiologic studies to identify intervention targets in Latinos and develop our intervention approaches. Through advocacy and research efforts, we are also working to integrate community-based health resources with more traditional healthcare services and settings.
