I am assistant professor of global health in the Department of Global Health and Population at the Harvard T.H. Chan School of Public Health (HSPH), and director of the International Health Systems Program. I am also assistant editor for health policy at Social Science and Medicine and faculty affiliate of the Center for International Development and the Harvard Center for Population and Development Studies. Previously I was a researcher in the World Bank Development Impact Evaluation (DIME) group and a post doctoral fellow at HSPH. My research focuses on the politics of health and health systems, and on evaluation of large-scale health programs and policies.
