Sara Allin is an Associate Professor of Health Policy at the Institute of Health Policy, Management and Evaluation, Dalla Lana School of Public Health, University of Toronto. She is also Director of the North American Observatory on Health Systems and Policies (NAO), a collaborative partnership and research centre focussed on sub-national and international health systems research to support evidence-informed policy making. Sara’s research and teaching span comparative health systems and policies, health system performance and health equity. As Director of the NAO, Sara leads a program of research that includes both rapid reviews in response to pressing health policy questions by local and international decision-makers and health sector stakeholders, and longer-term in-depth studies of health systems structures and reforms. She uses comparative methods, including qualitative case studies and quantitative analyses of survey and administrative data, and applies these to health policy questions within and across Canada, and in comparison with other high-income countries.
