Lindsey Smith is an Assistant Professor in the Department of Geography and Planning at The University of Toronto (St. George) and holds a PhD in Medical Sciences from the University of Cambridge. Dr. Smith’s research focuses on built and social environments as targets for promoting sustained healthy behaviours, social equity, and more environmentally sustainable communities. Her work incorporates the use of multi-disciplinary data, including GPS trajectory information, to enhance understanding of relationships between urban form, mobility, and health, as well as pathways to behaviour change. Recent projects explore household food environments, changes in physical activity in response to new transport infrastructure, and geographies of care.
