Biography

Dr. Allison Portnoy is an assistant professor of global health focused on vaccine decision science and policy. Her research integrates mathematical modeling, health economics, and epidemiology to inform vaccine development, introduction, and implementation strategies. She is particularly interested in understanding and quantifying the full public health, economic, and equity impacts of vaccination, with a focus on supporting evidence-based vaccine policy in low- and middle-income countries. Her ongoing work spans multiple disease areas, including human papillomavirus (HPV), measles, respiratory syncytial virus (RSV), and tuberculosis (TB), with additional expertise in vaccine delivery costs, implementation challenges, and global immunization policy. Her work has contributed to global vaccine decision-making through collaborations with international organizations and multidisciplinary research teams focused on improving access to life-saving immunization programs.

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.
