Dr. Persram is an Assistant Professor in the Department of Psychology at Toronto Metropolitan University. Dr. Persram earned his PhD in Psychology at Concordia University in Montreal with research interests in developmental psychology and youth development. Additionally, he completed postdoctoral fellowships at McGill University and Queen’s University, as well as collaborations across both institutions in association with PREVNet, a nationally recognized research network focused on promoting wellbeing and healthy youth relationships.

Dr. Persram’s research examines the correlates and consequences associated with youth interpersonal relationships. Specifically, he investigates how positive and negative experiences with siblings, peers, and romantic partners can promote and hinder youth adjustment. He is particularly interested in the unique and joint contributions of these relationships in relation to youth development and adjustment. Dr. Persram’s research also considers how contextual factors, such as gender identity and other sociodemographic aspects (e.g., family functioning, cultural background, SES) shape youth relationship development and individual adjustment. His work incorporates both quantitative and qualitative research methods.

Dr. Persram collaborates regularly with researchers and partners nationally (e.g., Ontario, Quebec), and globally (e.g., United States, United Kingdom, Colombia). His research has been funded by the Social Sciences and Humanities Research Council (SSHRC) and the Fonds de Recherche du Québec – Société et Culture (FRQSC).
