People show enormous variability in sexual preferences and attractions. Some preferences are very stable, and may even have prenatal origins. Other preferences are more labile, showing changes over time. Most sexual preferences are innocuous, but some lead to problematic or criminal behaviours.

In the Sex, Crime, and Evolution Research Laboratory we conduct research on the origins of the paraphilias, the causes of sexual crimes, and the reasons for sex differences in physiological sexual arousal. In addition, in collaboration with the University of Ottawa’s INSPIRE laboratory, we pursue research to develop new measures of sexual responses and research to determine the role of anxiety in sexual arousal using physiological measures (i.e., EMG and skin conductance). In collaboration with The Royal’s Institute of Mental Health Research, we also conduct research on the assessment and treatment of hypersexuality and paraphilic interests associated with sexual crimes, and research on the connection between psychological disorders and the paraphilias.
