Research Interests:<\/strong><\/h4>\n

I am the Director of the Mental Health and Addictions Laboratory in which we examine why people engage in behaviours that harm their health and how group contexts shape psychological well-being and intergroup behaviour.<\/p>\n

One line of research focuses on transdiagnostic factors\u2014psychological processes like overvalued ideation, perfectionism, and impulsivity\u2014that cut across traditional diagnostic boundaries. Using experimental studies, longitudinal designs, and daily experience-sampling methods, my research uncovers how these processes work together to sustain behaviours such as disordered eating and gambling. This work contributes to a developing transdiagnostic model of mental health and aims to inform more effective prevention strategies and interventions.<\/p>\n

A second line of research examines the mental-health implications of group membership. Drawing on social identity theory and clinical\/health psychology, we investigate how group-related experiences\u2014such as feeling threatened, marginalized, or emotionally connected to one\u2019s group\u2014shape well-being and intergroup behaviour. We are currently developing and researching the construct of collective anti-mattering<\/em>, which captures the belief that one\u2019s group does not matter to outgroups or society. Our work examines how this perception influences emotions, political attitudes, coping responses, and mental-health outcomes.<\/p>\n
