Keywords: health psychology; HIV/AIDS; clinical trials, community-based research

I received my doctorate in clinical psychology from Temple University. After graduate school, I completed a post-doctoral fellowship at Emory University School of Medicine, through which I received training at the Division of HIV/AIDS Prevention of the U.S. Centers for Disease Control and Prevention. I then worked for four years as an Assistant Professor at York University before joining the Department of Psychology at Ryerson in 2007.

I currently have 4 CIHR grant-funded studies. The most recently funded is a pilot study combining social anxiety treatment and HIV prevention for HIV-negative gay and bisexual men. The second is a randomized controlled trial (RCT) examining the use of motivational interviewing to improve sexual health and HIV/sexually transmitted infection prevention among HIV-positive gay and bisexual men. This study will be conducted in two sites: the AIDS Committee of Toronto and Positive Living British Columbia, in Vancouver. Third, with Dr. Nathan Smith at McGill University in Montreal, I am also piloting a new cognitive-behaviourally based sexual health and HIV prevention intervention for 18-25 year old HIV-negative gay and bisexual men. Lastly, my colleagues and I are conducting a longitudinal study of protective factors and risk factors for unprotected anal intercourse among 400 HIV-negative gay and bisexual men. I am also conducting smaller studies with youth populations, including homeless youth, incarcerated youth, and youth in Sri Lanka. For more information on my research and teaching, please see
