Dr. Flett holds a Tier 1 Canada Research Chair in Personality & Health, and is a Fellow of the Association for Psychological Science. Previously, he was the Associate Dean of Research and Graduate Education in York's Faculty of Health, as well as a director of LaMarsh. Dr. Flett is most recognized for his seminal contributions to research and theory on the role of perfectionism in psychopathology, which has received widespread national and international attention. Dr. Flett explores the relationship between perfectionism and psychological disorders, including eating disorders and postpartum depression. He is expanding his research to include the role of perfectionism in the treatment of and recovery from physical and mental illnesses. He is also taking a closer look at the role of perfectionists in contributing to stress and distress in their adolescent children, and the transmission of this personality trait from parent to child. Other research examines the protective role of feelings of mattering to other people, and the role of risk and resilience factors in well-being. His work has been supported by the Canadian Institutes of Health Research and the Social Sciences and Humanities Research Council of Canada.
