Bernhard Kühn, MD

  • Associate Professor of Pediatrics and Director, Pediatric Institute for Heart Regeneration and Therapeutics (I-HRT)
  • Associate Director, Richard King Mellon Foundation Institute for Pediatric Research

Understanding the unique workings of heart muscle cells - cardiomyocytes - is the passion of physician-scientist Bernhard Kühn. He and his team of researchers are focused on discovering ways to make cardiomyocytes replicate and proliferate, so as to enable the heart to heal itself in cases of heart failure or congenital defects.

A pioneer in this area of study, Kühn is the recipient of numerous grants and awards, including the American College of Cardiology's prestigious Young Investigator Award, the Basil O'Connor Award from the March of Dimes Birth Defects Foundation, and Scientist Development Grant from the American Heart Association, to name a few.
