Forensic Research Director at the Royal Ottawa Health Care Group and Associate Professor of Psychiatry, University of Toronto

I received a B.Sc. in Biopsychology from the University of British Columbia (1989) and completed my M.A. (1992) and Ph.D. (1997) in Clinical Psychology from Queen’s University in Kingston, Ontario, Canada.

I currently work as the forensic research director at the Royal Ottawa Health Care Group, after working for over 14 years at the Centre for Addiction and Mental Health in Toronto, Canada.

I have published extensively on paraphilias and sexual offending and regularly present at scientific meetings and professional workshops on these topics. I have also appeared in a variety of media outlets to talk about these topics, including CBC Radio One, CBC Newsworld, CTV, Global Television, TVO, The Globe and Mail, The National Post, The New Yorker, The Atlantic, The Economist, and Maclean’s magazine.

My research has been funded by the Ontario Mental Health Foundation, Social Sciences and Humanities Research Council, Canadian Institutes of Health Research, Correctional Service of Canada, and Mental Health Commission of Canada.

My main research interests are pedophilia; sexual offending against children; child pornography; risk assessment; mentally disordered offenders; and program evaluation. I am currently on the editorial boards of Sexual Abuse (Editor-niece-Chief), Archives of Sexual Behavior, Journal of Sex Research, and Law and Human Behavior, and provide ad hoc reviews for many other journals, including the Journal of Abnormal Psychology, Journal of Consulting and Clinical Psychology, and Law and Human Behavior.
