Associate Professor, Department of Psychology

Jonathan A. Weiss, Ph.D. (York University), is a Clinical Psychologist registered with the College of Psychologists of Ontario. He completed a pre-doctoral internship at Surrey Place Centre (Toronto) and a post-doctoral fellowship in the Dual Diagnosis Program at the Centre for Addiction and Mental Health, and was a fellow in the Department of Psychiatry at the University of Toronto.

His research focuses on the prevention and treatment of mental health problems in people with autism spectrum disorders and/or intellectual disabilities across the lifespan. He conducts studies into how people with developmental disabilities access mental health care in Ontario, and is interested in their health service needs, their emergency service use, and their experiences of psychiatric crisis. Families play a critical role in the health of people with developmental disabilities by providing them with care and enabling their access to health services, and he is currently focused on learning about the experience of family caregivers. He is interested in program development and evaluation, and in particular on the impact of Special Olympics on the psychological well-being of participants, and of cognitive-behavioural and social skill interventions to promote resilience and improve the mental health of children and adults with developmental disabilities.

Dr. Weiss holds the CIHR Chair in Autism Spectrum Disorders Treatment and Care Research, as well as operating funds from the Canadian Institutes of Health Research and Social Sciences and Humanities Research Council. He also holds a New Investigator Fellowship from the Ontario Mental Health Foundation.
