Teaching Interests

My teaching interests relate to all areas of my graduate and postdoctoral training in social, developmental, and forensic psychology. Specifically, I teach Survey of Social Psychology and Survey of Developmental Psychology, Contemporary Issues in Social Psychology and Contemporary Issues in Developmental Psychology, and Introduction to Forensic Psychology. I also teach Introduction to Psychology. I am open to supervising senior independent projects and I am willing to take up to two honours students each year.

Research Interests

My program of research addresses the impact of technology on the social and emotional development of children, adolescents, and young adults. More specifically, I am interested in the longitudinal effects of risk and protective factors (measured at both individual and contextual levels) on cyber bullying and victimization, and on behavioural and mental health problems. I am always willing to talk about my research and I am open to new ideas that could make for an interesting project.
