Abstract

Jeremy Walston helped transform frailty from a clinical syndrome into a biologically grounded condition, linking chronic inflammation, mitochondrial dysfunction, and impaired stress responses to loss of physiologic reserve. His leadership of the Johns Hopkins OAIC and SPRING studies advanced translational geroscience and trained a generation of investigators.
