Josh Ehrlich is a population health scientist and global aging expert, bridging epidemiology, demography, and public policy to understand how societies can adapt to aging populations. His work places particular emphasis on eye health as a driver of healthy longevity, with a focus on low- and middle-income countries.

As the Paul R. Lichter Research Professor at the University of Michigan and Associate Director of the Center for Global Health Equity, Dr. Ehrlich leads LOSHAK, a transformative population-level platform for studying aging in East Africa, which provides critical data to challenge global assumptions about health, retirement, and well-being. His research also explores sensory health - with a focus on global eye health - as a lens to understand aging, health, and well-being through initiatives like SENSE Network and Mi-SHARC, collaboratives that are dedicated to interdisciplinary research, training, and policy translation.

An ophthalmologist trained in epidemiology, Dr. Ehrlich holds tenured faculty appointments at the University of Michigan Medical School (Ophthalmology and Visual Sciences) and Institute for Social Research (Survey Research Center). He is also an Honorary Associate Professor at the London School of Hygiene and Tropical Medicine. His research and commentary have appeared on podcasts and in outlets such as The New York Times, CNN, The Conversation, Milbank Quarterly, and Lancet Global Health, and he has advised policymakers and media on how science can inform fairer, healthier aging for all societies.

Committed to public engagement and mentorship, Dr. Ehrlich writes and speaks on global aging and population science for audiences beyond academia, and trains the next generation of researchers in global health equity, epidemiology, and population health science.
