Research interests/expertise

The key objective of my program of research is to foster healthy relationships for children, adolescents, and young adults in online and offline environments. My program of research broadly addresses the role of digital technology in the social and emotional development of children, adolescents, and young adults.  I am particularly interested in the longitudinal effects of risk and protective factors (measured at both individual and contextual levels) on cyber bullying and cyber victimization, and on behavioural and mental health problems. I am always willing to talk about my research with students and I am open to new ideas that could make for an interesting project.


Teaching

My teaching interests relate to all areas of my graduate and postdoctoral training in social, developmental, and forensic psychology. Specifically, I teach survey courses in developmental and social psychology (PSYC 2025 and 2125), and contemporary issues courses in developmental and social psychology (PSYC 3025 and 3125). I also teach a required course in Introduction to Psychology II (PSYC 1001), an elective course in Forensic Psychology (PSYC 2150),and Independent Project in Psychology (PSYC 4950).  I am open to supervising senior honours projects and I am willing to take up to two students each year.
