Chan School of Public Health, and faculty of the Harvard Center for Health Decision Science. Professor Menzies uses decision science and quantitative research to understand the consequences of major policy change, and to design effective disease control programs where resources are limited. His research combines empirical data with mathematical modeling to examine infectious disease control policy in high burden settings. Currently, his focus is on the intersection of HIV and TB epidemics in sub-Saharan Africa and other high-burden settings.
