Targeting Healthspan has personal (to elderly, HIV patients, cancer therapy survivors and astronauts) benefits and longevity dividends. We cannot afford not to do it.

Nir Barzilai, M.D.

Director of the Institute for Aging Research at Albert Einstein College of Medicine & Director of the Paul F. Glenn Center for the Biology of Human Aging Research

Dr. Nir Barzilai is the director of the Institute for Aging Research at the Albert Einstein College of Medicine and the Director of the Paul F. Glenn Center for the Biology of Human Aging Research and of the National Institutes of Health’s (NIH) Nathan Shock Centers of Excellence in the Basic Biology of Aging. He is the Ingeborg and Ira Leon Rennert Chair of Aging Research, professor in the Departments of Medicine and Genetics, and member of the Diabetes Research Center and of the Divisions of Endocrinology & Diabetes and Geriatrics.


  • Centenarians. Dr. Barzilai hypothesizes that centenarians have protective genes that allows the delay of aging and protect against age-related diseases. Dr. Barzilai leads a program in which he observes phenotypes, DNA, and cells from the Ashkenazi Jewish families with exceptional longevity. Through this initiative, he has observed at Einstein over 2600 samples of exceptional longevity, (of which ~670 are centenarians) discovering underling genomic differences associated with longevity along the way.

  • Dr. Barzilai founded the Longevity Genes Project (LGP) which is a cross-sectional, on-going collection of blood and phenotype from families with centenarian proband.

  • His lab has also identified several central pathways that specifically alter body fat distribution, insulin action and secretion by intraventricular or hypothalamic administration of several peptides that are modulated by aging including: Leptin, IGF-1, IGFBP3 and resveratrol.

Awards and Honors

  • Dr. Barzilai holds an NIH Merit award that focuses on the metabolic decline of aging, hypothesizing that the brain leads this decline.
