Dr. Leo Wilton is a professor in the Department of Human Development at the State University of New York at Binghamton and a clinical psychologist with research expertise in the design of culturally congruent HIV prevention and care interventions for Black men who have sex with men. His primary research interests focus on health disparities and inequities (HIV and AIDS), Black psychological development and mental health, community-based participatory research (CBPR), and mixed- and multi-methods research. His scholarly research on the HIV epidemic examines the intersectionality of race, gender, and sexuality as situated in macro- and micro-level inequities in Black communities.

His research explores how socio-structural and cultural contexts influence people's development and well-being within Black communities. He has served as PI or Co-PI on several NIH-funded research studies. He served as the lead behavioral scientist for HPTN 073, investigating PrEP initiation, acceptability, and feasibility for Black MSM in three U.S. cities. He served on the protocol team and provided scientific leadership for HPTN 061 (The Brother's Study), the largest prospective cohort study of Black MSM in six U.S. cities. He was the lead research scientist for the randomized controlled trial of Many Men, Many Voices: An HIV/STI Behavioral Intervention for Black MSM.
