In addition, she holds a faculty appointment at the University of Toronto (Department of Psychiatry) and is a member of the University Health Network Centre for Mental Health. She received her Ph.D. in Clinical Psychology from the University of Calgary, and completed an accredited internship at the University of British Columbia. Following graduation, she completed a postdoctoral fellowship at the University of Toronto and Sunnybrook Health Sciences Centre (Mood and Anxiety Treatment and Research Program).

Dr. Cassin’s clinical and research interests are in the area of disordered eating, obesity, and bariatric (weight loss) surgery. She is a Registered Clinical and Health Psychologist. Her current program of research focuses primarily on psychosocial predictors of bariatric surgery outcome, and psychosocial interventions with the potential to improve outcomes, including cognitive behavioural therapy and motivational interviewing. She also investigates health care innovations that increase treatment accessibility, such as telephone-based interventions.
Dr. Cassin has taught a variety of courses on psychopathology and evidence-based treatments at Ryerson University (Psychological Disorders, Advanced Psychopathology Seminar, Clinical Psychology, Eating Disorders, Cognitive Behavioural Therapy), and provided clinical supervision to many graduate students completing practicum placements at the Psychology Training Clinic at St. Michael’s Hospital.
