Health disparities and HIV


Diana Sheehan is an Associate Professor in the Department of Epidemiology at the Robert Stempel College of Public Health and Social Work at Florida International University (FIU). She aims to contribute to health equity among the Latino population via epidemiologic studies that identify disparities along the HIV care continuum and via the design and testing of evidence-based interventions. Her current studies are developing and assessing the efficacy of Just-In-Time Adaptive Interventions (JITAI) and stepped care interventions for improving antiretroviral therapy adherence among Latino sexual minority men. Dr. Sheehan’s studies use various methodologies such as Ecological Momentary Assessments (EMA) and Sequential Multiple Assignment Randomized Trial (SMART) designs. Dr. Sheehan’s work has been funded by the National Institute on Minority Health and Health Disparities (NIMHD), the National Institute on Drug Abuse (NIDA), , the HIV Prevention Trials Network (HPTN), and the Robert Wood Johnson Foundation. In addition to her research, Dr. Sheehan is dedicated to advancing the research careers of minority investigators through various appointments, including as a co-leader of FIU-RCMI’s Investigator Development Core and core faculty of FIU’s Health Disparities Initiative.
