Health disparities and HIV


Diana Sheehan is an Associate Professor in the Department of Epidemiology at Florida International University (FIU). Her research focuses on identifying gaps and improving outcomes along the HIV care continuum, particularly for Latinos living with HIV in the United States and Latin America. Currently, Dr. Sheehan is leading an ecological momentary assessment (EMA) study that examines antiretroviral therapy adherence and the feasibility of a related Just-In-Time Adaptive Intervention (JITAI) among Latino men who have sex with men.

Dr. Sheehan’s work has been funded by the National Institute on Drug Abuse (NIDA), the National Institute on Minority Health and Health Disparities (NIMHD), the HIV Prevention Trials Network (HPTN), and the Robert Wood Johnson Foundation. Additionally, Dr. Sheehan is dedicated to advancing the research careers of minority investigators, both as a faculty under the FIU-Health Disparities Initiative (FIU-HDI) and as a co-investigator on the FIU Center for Reducing Health Disparities in Substance Abuse & HIV in South Florida (FIU-RCMI).
