Hannah has a Master of Science in Public Health and a Certificate in Demographic Methods from the Department of Population, Family, and Reproductive Health at the Johns Hopkins Bloomberg School of Public Health. She also holds a Bachelor of Arts in Anthropology from the University of Texas at Austin. Her research interests focus broadly on the social determinants of health, with a particular interest in how the inequitable distribution of material resources and stress exposure throughout the life course produces racial and socioeconomic health inequality. Before joining the Graduate Group in Demography at Penn, Hannah was leading operations for a large mobile phone-based population health survey in 11 countries of Sub-Saharan Africa and South Asia. With funding from the Bill and Melinda Gates Foundation, the project collected nationally representative data on family planning, abortion, maternal newborn health, adolescent health, primary health care, and water, sanitation, and hygiene (WASH).
