The Paul F. Glenn Center for Biology of Aging Research at the Salk Institute was initially established in January 2009. Led by Salk professors Dr. Jan Karlseder and Gerald Shadel, the Center draws from Salk’s leading laboratories specializing in genetic analysis, stem cell biology and metabolism research to address the overarching goal of defining a healthy lifespan, or healthspan, and to answer one of the most elusive questions in biology: Is there a defined biological process of aging that is universal to all organisms?
