Zahida Khan, MD, PhD
Assistant Professor of Pediatric Gastroenterology and Pathology

Dr. Khan is an instructor in Pediatric Gastroenterology and Pathology. Her clinical appointment is at Children's Hospital of Pittsburgh (CHP). She is also a member faculty of the McGowan Institute for Regenerative Medicine. Dr. Khan has longstanding clinical and research interests in pediatric hepatology and liver transplant. Her research focuses on cellular approaches to liver regeneration and transplantation. Dr. Khan studies mechanisms of hepatocyte regeneration in alpha-1 antitrypsin deficiency, the most common inherited cause of pediatric liver disease and transplantation. Her work investigates critical cellular signals for liver regeneration, including (1) bile acid signaling, and (2) the liver stem cell marker LGR5 (Leucine-rich repeat-containing G-protein coupled receptor 5). Dr. Khan plans to extend these studies by developing cellular and molecular therapies for liver-based metabolic diseases.
