I received my B.A. in Psychology from the University of Rochester and my M.A. and Ph.D. in Clinical/Community Psychology from the University of South Florida. I am now an Adjunct Professor at the Centre for School Mental Health and Research Scholar at the Centre for Research and Education on Violence Against Women and Children, in the Faculty of Education. I am an elected Fellow of the Royal Society of Canada. I was formerly the Head of the Centre for Addiction and Mental Health (CAMH) Centre for Prevention Science and Professor of Psychiatry and Psychology at the University of Toronto (2002-2016). I held the inaugural RBC Chair in Children’s Mental Health from 2002 to 2012 and served as Editor-in-Chief of Child Abuse & Neglect: The International Journal from 2007 to 2012.

For over 40 years I have been active in developing and evaluating violence and abuse prevention initiatives for children and youth. I have broad research and clinical interests in abnormal child and adolescent psychology, with a special focus on child abuse, domestic violence, and developmental psychopathology. My current major research activity relates to the Fourth R, a school-based program to promote healthy, non-violent relationships among youth (www.youthrelationships.org).
