Biography

Dr. Cassin is an Associate Professor and Director of the Healthy Eating and Lifestyle (HEAL) Lab at Ryerson University. In addition, she holds a faculty appointment at the University of Toronto (Department of Psychiatry). She received her Ph.D. in Clinical Psychology from the University of Calgary, and completed an internship at the University of British Columbia. Following graduation, she completed a postdoctoral fellowship funded by the Ontario Mental Health Foundation at the Mood and Anxiety Treatment and Research Program at Sunnybrook Health Sciences Centre. Prior to joining the Department of Psychology at Ryerson University, she held staff clinical psychologist positions in the Mood and Anxiety Program at the Centre for Addiction and Mental Health, and the Bariatric Surgery Program at Toronto Western Hospital.

Research Interests

Dr. Cassin’s research interests are in the area of disordered eating, obesity, and bariatric (weight loss) surgery. The research she completed during her doctoral training focused on the conceptualization of binge eating as a behavioural addiction, and the potential therapeutic implications that arise from this conceptualization.  She is particularly interested in the impact of readiness for change on treatment outcome, as well as treatment approaches aimed at resolving ambivalence and enhancing readiness for change, such as motivational interviewing.

Her current research interests include psychosocial predictors of bariatric surgery outcome, and psychosocial interventions with the potential to improve outcomes. Current projects include a CIHR-funded study on cognitive behavioural therapy for bariatric surgery patients and a study on motivational interviewing for post-operative bariatric surgery patients.

Clinical Interests

 Dr. Cassin is particularly interested in the evidence-based assessment and treatment of eating disorders, anxiety disorders (i.e., social phobia), and obsessive-compulsive disorder. She takes a collaborative, cognitive-behavioural approach to treatment and frequently incorporates motivational interviewing strategies to help prepare individuals for CBT when ambivalence about making changes poses a barrier to treatment.

Teaching Interests

Dr. Cassin teaches a variety of undergraduate and graduate courses related to psychopathology, including Psychological Disorders, Clinical Psychology, Advanced Psychopathology Seminar, and Eating Disorders. In addition, she provides clinical supervision to graduate students completing practicum placements at the Clinical Psychology Training Clinic at St. Michael’s Hospital Department of Family and Community Medicine. In 2014, Dr. Cassin was awarded a Dean’s Teaching Award.
