Dr. Nir Barzilai is a geroscientist, Chaired Professor of Medicine and Genetics, and the founder and principal investigator of the Einstein Nathan Shock Center and the Glenn Center for Excellence in Biology of Aging. He also studies families of centenarians that have provided genetic and biological insights on the protection against aging—with several drugs developed based, in part, on these paradigm-changing studies. He is also leading the TAME (Targeting/Taming Aging with Metformin) trial to prove to the FDA that aging can be delayed and to allow for next-generation interventions.
