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. I study the role of digital technology (e.g., cyber bullying, social media, video gaming, sexting, cyber dating violence) in the social and emotional development of children, adolescents, and young adults.
Teaching
- 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), Senior Seminar in Psychology (PSYC 4925), and Independent Project in Psychology (PSYC 4950).
- I typically supervise honours student projects and I am willing to take up to two students each year.
