Ken Zucker

Kenneth J. Zucker (born 1950) is an American-Canadian psychologist and sexologist. He was named Editor-in-Chief of Archives of Sexual Behavior in 2001. He was Psychologist-in-Chief at Toronto's Centre for Addiction and Mental Health and Head of the Gender Identity Service until December, 2015. Zucker is a professor in the Departments of Psychiatry and Psychology at the University of Toronto.

He collaborated with Susan Bradley, collecting clinical and research data over a period of twenty years and became an international authority on gender identity disorder in children (GIDC) and adolescents. In 2007, Zucker was chosen to be a member of the American Psychological Association Task Force on Gender Identity, Gender Variance, and Intersex Conditions, and in 2008 he was named chair of the American Psychiatric Association workgroup on "Sexual and Gender Identity Disorders" for the 2012 edition of the DSM-5. He previously served on workgroups for the DSM-IV and the DSM-IV-TR.

His views are controversial in the transgender community, which led to an external review of the clinic in 2015.

Zucker was born in 1950 to Jewish parents and grew up in Skokie, Illinois. Zucker received his B.A. from Southern Illinois University, his M.A. from Roosevelt University, and his Ph.D. from University of Toronto in 1982. He holds a certification from College of Psychologists of Ontario.
