Dr. Allison Portnoy is an assistant professor of global health focused on vaccine decision science and policy. Her research includes economic evaluation and public health policy, simulation modeling, health equity, and the impact of vaccination on population health and economic outcomes. She is particularly interested in broadening the value of vaccination in high-burden settings. Her ongoing work spans multiple diseases areas, including human papillomavirus (HPV), measles, and tuberculosis (TB).

Dr. Portnoy received a Doctor of Science from the Department of Global Health and Population and completed a postdoctoral fellowship at the Center for Health Decision Science, both at the Harvard T.H. Chan School of Public Health. Her previous education includes an MSPH in Health Policy & Management from the Johns Hopkins Bloomberg School of Public Health and a BA in International Relations from Stanford University. She previously worked as a health economist at the International Vaccine Access Center at Johns Hopkins, and conducted research projects with the World Health Organization, Agency for Healthcare Research and Quality, and the University of Washington in Seattle.
