Associate Professor, Psychology
My teaching focuses largely on applying psychological principles to help promote health and well-being across differing populations. I teach courses on health psychology, adolescent risk behaviours and statistics, among others.
Summary of Research:
- My research program focuses on social contributions to health-risk behaviour in adolescence and emerging adulthood.
- Much of my research focuses on the multifaceted role of peer influence and peer group dynamic on alcohol use and related risks. I recently conducted the first longitudinal study on university students’ intact drinking groups to examine how group factors, including drinking norms and individuals’ status within the group predict consumption patterns over time. Other current research aims to apply these findings to evidence-based intervention programming.
