S. Jay Olshansky received his Ph.D. in Sociology/Demography from the University of Chicago in 1984. He is Emeritus Professor in the School of Public Health at the University of Illinois Chicago, a Research Associate at the Center on Aging at the University of Chicago, and former Chief Scientist of Lapetus Solutions, Inc., a company he co-founded. Dr. Olshansky’s research has focused on the biology and demography of human aging, including estimates of the upper limits to human longevity, the health and policy implications of population aging, forecasts of population size and age structure, and the scientific pursuit of interventions designed to slow aging in humans. His work also examines the societal and economic implications of longevity science, including applications to mortality and longevity-related financial products, as well as the global effects of emerging and re-emerging communicable diseases. Over the past four decades, Dr. Olshansky and colleagues helped develop the modern biodemographic paradigm of mortality, emphasizing the biological foundations of survival, aging, and the dying-out process in living organisms. His work has contributed substantially to contemporary scientific understanding of aging as a biological process and to the emerging field of geroscience, which links the biology of aging to chronic disease risk and public health outcomes. Dr. Olshansky is the author or editor of several influential books on aging and longevity, including The Quest for Immortality: Science at the Frontiers of Aging (Norton, 2001), A Measured Breath of Life (2013), The Rise of Generians (2020), and Pursuing Wealthspan (2020). He also co-edited Aging: The Longevity Dividend (2015) and Aging: Geroscience as the New Public Health Frontier (2024). His scientific and public-policy contributions have earned numerous honors and awards. These include the Donald P. Kent Award from the Gerontological Society of America, the Irving S. Wright Award from the American Federation for Aging Research, the Alvar Svanborg Award, the Glenn Award from the Glenn Foundation for Medical Research, and the Kathy N. Johnson Achievement Award from Home Care Assistance. He was also named a Next Avenue Influencer in Aging, served as a Senior Fulbright Scholar in France, and was recognized by the Mayo Clinic with the George Randolph and Patricia Scott Visiting Professorship on the Physiology of Aging. Dr. Olshansky has held leadership and advisory roles in both scientific and private-sector organizations. He served on the boards of the American Federation for Aging Research and U.S. Preventive Medicine, and on the Board of Scientific Advisors for PepsiCo. His recent work has increasingly connected aging science with finance, insurance, and longevity-risk assessment. In 2022, Dr. Olshansky testified before the United States House Committee on Science, Space, and Technology on aging and geroscience, discussing how advances in the biology of aging may transform medicine, public health, and the experience of growing old. He has also served as an expert legal witness on lifespan estimation and mortality assessment for individuals and populations.
