Research Description

Dr. Horvath’s research primarily focuses on developing and testing HIV prevention and treatment mHealth interventions for sexual and gender minorities. He currently leads or co-leads NIH-funded studies to develop and test mHealth interventions for adults and youth living with HIV, HIV-negative transgender youth, men who have sex with men living with HIV and who use stimulant drugs, young sexual minority men who take pre-exposure prophylaxis (PrEP), and African American women living with HIV. In addition, Dr. Horvath co-leads a study of formative work to develop a technology-based intervention to optimize on-demand PrEP strategies.
