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 3 intervention studies underway. The first  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 is being conducted in two sites: the AIDS Committee of Toronto and Positive Living British Columbia, in Vancouver. This intervention is called Gay Poz Sex, or GPS. The third study adapts the GPS program into a one-on-one counselling approach, and administers GPS to both HIV-negative and HIV-positive gay and bisexual men. We will be running this adapted program in 5 sites across the country. I collaborate with other researchers on several other projects, such as studies of non-monogamy, pre-exposure prophylaxis, combination HIV prevention, women-centred HIV care for women living with HIV, and use of the internet for HIV prevention among young gay and bisexual men.

    I also hold a CIHR Team Grant in Boys’ and Men’s Health, which involves researchers in HIV prevention and community-based organizations across Canada. This project will involve a cross-sectional study of prevalent and recent infections of HIV and other sexually transmitted and blood-borne infections (STBBIs) among 2,100 gay, bisexual, and other men who have sex with men in Vancouver, Toronto, and Montreal. Recently, we completed a CIHR-funded  3 time point study of protective factors and risk factors for condomless anal sex among 470 HIV-negative gay and bisexual men, and we are in the process of analyzing and disseminating the results of this study.
