Teaching & Supervision

discrimination prejudice psychometrics sexuality stereotyping

I teach a number of courses; however, the ones I instruct most often are Psychology 227 (Human Sexuality) and Psychology 427 (Sexual Minority Issues in Social Psychology).



Currently, I am supervising one doctoral student (Mannie Mirzaei) and one MA student (Terri Croteau).  All of my students, past and present, are actively engaged in the publication process, with co-authored papers appearing in outlets such as Violence against Women, Journal of Homosexuality, Journal of Sex Research, Journal of Lesbian Studies, Sexuality & Culture, Psychology & Sexuality, Journal of Sexual Medicine, and Porn Studies



Stereotyping, prejudice, and discrimination body image feminist psychology film studies human sexuality masculinity pornography psychometrics queer studies

My publication list underscores the diversity of my research interests. However, two dominant themes are evident: 1) I conduct research on topics relevant to the lives of sexual minority persons (e.g., gay men, lesbian women, asexual persons, etc.); and 2) I am interested in the ways in which cultural artefacts such as film and music disseminate messages about minoritized groups (e.g., women, gay men, trans persons, etc.).     

Education & Training

I completed my BSc (1st class honours) at the University of Victoria; my MSc at Memorial University of Newfoundland; and my PhD at Queen's University (Kingston).
