I am Professor Emeritus at the Centre for School Mental Health and Research Scholar at the Centre for Research and Education on Violence Against Women and Children, 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).
