Research Interests

Iris is a graduate student in the IMPACT lab at Ryerson and also conducts research and clinical work within the HEAL lab. She works as a therapist delivering telephone-based cognitive behavioural therapy to individuals who have undergone bariatric surgery, and has in the past conducted qualitative research on interpersonal relationships and body image in bariatric surgery patients. She is particularly interested in the overlap between disordered eating and trauma, and her research aims to examine predictors of treatment outcome to enhance patient care.
