Description: Morgan Levine, Ph.D., developed the phenotypic aging clock called PhenoAge and is a Founding Principal Investigator at Altos Labs, a biotech company that seeks to understand the mechanisms that drive the aging process and age-related diseases with the hope of identifying possible interventions. Additionally, Dr. Levine is an assistant professor of pathology at the Yale University School of Medicine, where her research focuses on the science of biological aging. Dr. Levine completed a postdoctoral fellowship with previous guest Dr. Steve Horvath, a pioneer in the field of epigenetic clocks.
