Ronald Langevin

Ronald Lindsay André "Ron" Langevin (born September 28, 1940) is a Canadian forensic psychologist at the University of Toronto. He is the founding editor of Annals of Sex Research, now titled Sexual Abuse: A Journal of Research and Treatment.

Life and career Langevin was born in Montreal and earned a Ph.D. in psychology from University of Toronto in 1970. He wrote materials for the Canadian Council for Research in Education before taking a position at the Clarke Institute of Psychiatry, where he worked with Kurt Freund.

Langevin argued against the effectiveness of reparative therapy in 1985. He served as an expert witness in a sexual abuse trial in 1989. In 1989 also, Langevin published findings suggesting a correlation between sex offenders and traumatic brain injury, though he suggested caution in the use of the findings, as half his subjects were alcohol abusers.

He is director of Juniper Associates Psychological Services and is an associate professor in the Law & Mental Health program at University of Toronto. He has also published materials through Juniper Press. Langevin is a charter member of the International Association for the Treatment of Sexual Offenders (IATSO).
