Research Interests

My research program focuses on personality as a risk factor for psychopathology using longitudinal methods, with constructs measured using a multi-method measurement approach. Specifically, I focus on two key areas: (a) Perfectionism as a risk factor for mood problems; and (b) personality traits and motivations as risk and protective factors for alcohol misuse.
