Internationally recognized geriatrician Jeremy Walston, the Raymond and Anna Lublin Professor of Geriatric Medicine and Gerontology, died on June 10. He was 64.

A renowned expert in geriatric medicine, Walston made influential contributions to research, education and clinical care at Johns Hopkins Medicine and around the world. He developed the Frailty Assessment Calculator, a measurement system that has become the leading tool for hundreds of studies, and is increasingly being integrated into clinical practices to improve risk assessment and care planning for older adults.

As director of the Johns Hopkins Human Aging Project (HAP), deputy director of the Division of Geriatric Medicine and Gerontology, principal investigator of the Johns Hopkins Older Americans Independence Center, and co-director of the Biology of Healthy Aging program, Walston performed translational research on the biological characteristics that promote resiliency and healthy aging.

The HAP, launched in 2021, brings together a multi-disciplinary group of experts across Johns Hopkins to accelerate knowledge of aging and solutions to aging-related problems.

“The cohesiveness of the HAP speaks volumes not only to Jeremy’s scientific excellence but also to his many admirable personal qualities,” says David Hellmann ’77, director of the Johns Hopkins Center for Innovative Medicine, which supports the HAP. “Because of his humility, generosity of spirit and impish sense of humor, Jeremy became a treasured friend to us and to so many others.”

Walston, who earned his M.D. from the University of Cincinnati College of Medicine, completed a residency in general internal medicine and a fellowship in geriatric medicine and gerontology at Johns Hopkins Bayview Medical Center in 1993. He remained at Johns Hopkins for the rest of his career.

Walston’s research — which includes nearly 300 publications and book chapters — built bridges between disciplines and had a profound influence on subspecialists and biologists outside the field of aging research. His mentorship helped launch the careers of numerous prominent geriatricians and gerontologists, earning him the 2025 Dean’s Distinguished Mentoring Award.

Walston is survived by his husband and partner of more than 43 years, George Lavdas; two sons, Oliver Walston-Lavdas and Alexander Walston-Lavdas; as well as other family members.
