Research interests

My primary research interest is in the aetiology of young adult heavy and problem alcohol use. My research aims to explicate the positive and negative reinforcement pathways that lead to problematic drinking, particularly for those transitioning from adolescence to early adulthood. Within this framework I examine the role of individual-level factors such as personality (i.e., behavioural inhibition/approach systems), social anxiety, and cognitive processes (e.g., self-regulatory and impulsive processes) to distinguish who is at risk and the inherent mechanisms. I also consider environmental and cultural context in models of risk and resilience.

In one line of my current work I use a mix of in-lab experimental studies, ecological momentary assessments (i.e., data collection by smartphone), and online prospective studies to test models of alcohol use risk among those transitioning into, through, and out of university. In another line of my work, in conjunction with community partners and a larger cross-Canada team of academic and non-academic collaborators, I use a mixed method approach to examine the role of Indigenous culture in youth resilience and abstinence from substance use.

I am a core member of the Concordia University Centre for Clinical Research in Health (CCRH)
