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 four doctoral students (Joshua Katz, Mark Kiss, Mannie Mirzaei, and Elly-Jean Nielsen) and two MA students (Terri Croteau and Carolina deBarros). They have conducted research on queer cultural expression, positive bisexual identity, gender non-binary microaggressions, lesbian camp, gay male pornography, masculinity threat, and the relationship between disgust and homonegativity. All of my students 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 undergraduate BSc at the University of Victoria; my MSc at Memorial University of Newfoundland; and my PhD at Queen's University (Kingston).
