Dr. Trevor Hart is the Director of the HIV Prevention Lab and Director of TMU’s new HOPE Centre for Gender and Sexual Minority People: the first and only Centre in Canada dedicated to combining health research aimed at understanding disparities in sexual and gender minority health, with the identification, testing, and implementation of counseling and other practice solutions for better health outcomes.

Currently, he is conducting a CIHR-funded randomized controlled trial (RCT) evaluating a new HIV prevention intervention designed to reduce HIV risk, social anxiety, and problematic substance use among gay, bisexual, queer, and other men who have sex with men (GBM). This ongoing study is called Sexual Confidence.

Dr. Hart is also a Site PI of the CIHR-funded Engage cohort study, which involves researchers in HIV prevention and community-based organizations across Canada. This project is a longitudinal study of prevalent and recent infections of HIV and other sexually transmitted and blood-borne infections (STBBIs) among 2,100 GBM in Vancouver, Toronto, and Montreal. Recently, the Engage team received CIHR funding to conduct a new study on how biomedical treatments for bacterial sexually transmitted infections are changing the incidence of sexually transmitted infections and related sexual behaviours among GBM.

Dr. Hart received his doctorate in clinical psychology from Temple University. After graduate school, he completed a post-doctoral fellowship at Emory University School of Medicine, through which he received training at the Division of HIV/AIDS Prevention of the U.S. Centers for Disease Control and Prevention. He then worked for four years as an Assistant Professor at York University before joining the Department of Psychology at Ryerson in 2007.  He has received several awards for his advancements to research and clinical work, including membership in the College of New Scholars, Arts, and Scientists of the Royal Society of Canada, Fellow of the Association for Behavioral and Cognitive Therapies (ABCT), a Toronto Metropolitan University Social Innovation and Action Research Award, and membership in the international Sigma Xi Honor Society of scholars and scientists.
