Dr. Abby Goldstein leads an innovative program of research exploring the unique needs, challenges and motivations of emerging adults with a focus on understanding their substance use, mental health, and well-being from a developmental lens. Her research uses methods that capture the day-to-day experiences and behaviours of emerging adults, and changes in these experiences as they transition into adulthood.

Dr. Chloe Hamza’s research program focuses on the development of mental health concerns in adolescence and emerging adulthood, particularly self-injurious behaviors (e.g., nonsuicidal self-injury, suicidal behavior). She is interested in identifying risk and protective factors for self-injury among students, as well developing best-practice recommendations to assist schools in supporting students who self-injure in a variety of educational contexts, including colleges and universities. She is an invited member of the International Consortium on Self-Injury in Educational Settings (ICSES), which is a group of leading researchers and clinicians committed to developing and disseminating evidence-informed guidelines to support students who self-injure. She also was selected to be a member of the University of Toronto’s Presidential & Provostial Task Force on Student Mental Health in 2019, tasked with making recommendations to improve mental health service delivery on campus. As an instructor, she currently teaches graduate courses on mental health in the classroom, and adolescent and emerging mental health at the Ontario Institute for Studies in Education.

Jeffrey Wardell, Ph.D.

Assistant Professor
Department of Psychology
Faculty of Health
York University | | 416-736-2100 ext. 44241


Dr. Wardell studies substance use behaviour, especially alcohol and cannabis use, with a focus on the developmental context of emerging adulthood. His research examines how personality, cognitive, social, and biological factors interact to increase risk for, or provide protection against, negative consequences and health risks of substance use. A current focus of his research is understanding the predictors and consequences of combined use of different substances, as well as medicinal and recreational motives for cannabis use among youth. Dr. Wardell’s work also investigates the role of stress and coping in substance use behaviour among young adults.
