Dr. Jaana Juvonen

Department of Psychology


Professor Juvonen studies teens’ relationships with their peers mainly in school contexts. She is particularly interested in the effects of school and classroom heterogeneity or diversity on friendships and emotional wellbeing of youth. A central goal of her work is to understand what types of environments promote social inclusion.

Guided by a social-contextual perspective, she conceptualizes schools and classrooms as ecological niches shaped by student composition. She is interested in various types of diversity (e.g., ethnic, body-weight, SES). Some of her latest research examines school-wide social norms that “police” conformity.
