Our Principal Investigator

She is particularly interested in how gender inequities and other social determinants of health affect people experiencing problem gambling and substance use, mental illness, poverty, homelessness and imprisonment. She has particular expertise in integrated knowledge translation approaches with community-based partners and with people with lived experience of addictions, mental health concerns and homelessness. She is a Scientist at the Centre for Urban Health Solutions, St. Michael’s Hospital; Scientist in the Mental Health and Addictions Program at the Institute for Clinical Evaluative Sciences; and, Associate Professor with the Dalla Lana School of Public Health and the Centre for Criminology and Sociolegal Studies, University of Toronto.


Arthur McLuhan

Postdoctoral Fellow

Arthur is a postdoctoral fellow at the Dalla Lana School of Public Health, University of Toronto and the MAP Centre for Urban Health Solutions, St. Michael’s Hospital, Toronto. He holds a PhD in Sociology from McMaster University.

As a sociologist who studies diverse social worlds—drug subcultures, seminaries, barbershops, refugee reception contexts, service agencies, addiction and reintegration programs—the moral order of everyday life has been a central theme that informs and integrates his research.

Arthur works with Dr. Matheson at MAP, where they are pursuing two streams of research: (1) problem gambling, poverty, and homelessness and (2) incarceration, traumatic brain injury, and comorbidities. This work is focused on developing evidence-based, stakeholder-informed mobile applications as an eHealth approach to reaching marginalized populations, providing them with tools for self-managing gambling, in the case of the former stream, and breaking the cycle of incarceration and enhancing the experience of reintegration, in the case of the latter stream. These projects represent one way Arthur has been extending beyond the academy to critically engage social issues in a public forum.

Arthur’s research has been published in multiple venues–such as Social Forces, Sociological Theory, Canadian Ethnic Studies, and Refuge—and received recognition from the Society for the Study of Social Problems and the Society for the Study of Symbolic Interaction.
