Research Activities

My research focuses on improving the health of people who are homeless or vulnerably housed and deepening our understanding of housing as a social determinant of health. My current research projects include a study of health care utilization in a sample of 1,191 homeless men, women, and families in Toronto; an observational cohort study of health and housing transitions among 1,200 homeless and vulnerably housed adults in Toronto, Ottawa, and Vancouver; and the Mental Health Commission of Canada’s “At Home” study, a randomized controlled trial of rent subsidies and mental health supports for individuals who are homeless and have mental health issues.
