Research Interests

My research program focuses on personality as a risk factor for psychopathology often analyzed using multilevel modelling and/or structural equation modelling. Specifically, I focus on two key areas: (a) Perfectionism as a risk factor for mood problems and well-being; and (b) personality traits and motivations as risk and protective factors for alcohol misuse. My current research focuses on the relationship between perfectionism and anxiety within statistics classrooms.
