BIO
José E. Diaz is a postdoctoral associate in the STAR Program at SUNY Downstate Health Sciences University and a fellow in the Research Education Institute for Diverse Scholars (REIDS) program at Yale University. Dr. Diaz’s research aims to advance our understanding of HIV- and substance use-related disparities among sexual minority adults, particularly Latinx sexual minority men. His current interests center on understanding and reducing the resurgent stimulant use epidemic among Latinx sexual minority men. He is currently assisting with an intervention study aiming to improve HIV care outcomes among stimulant-using sexual minority men living with HIV in the U.S. His ongoing work also includes the use of national data to examine substance use and mental health disparities through an intersectionality framework, and the examination of multi-level correlates of behavioral health outcomes among sexual minority men in New York City.
