My guest today is Dr. Collin Ewald who is a professor at the Health Sciences department at ETH Zurich. His lab focuses on understanding the extracellular matrix (ECM) and how it changes with age. Collin explains the role of the ECM in tissue repair, muscle strength, and overall longevity. In fact, Collin’s lab is also working on establishing the ECM as a biomarker for health and disease risk. So, studying the ECM can indeed tell us a lot about the aging process and ways to intervene.
