Andrew P. Feranchak, MD

  • Division Director, Gastroenterology, Hepatology and Nutrition, Carol Ann Craumer Endowed Chair for Pediatric Research, and Professor of Pediatrics

Andrew Feranchak, MD is the Director of the Division of Pediatric Gastroenterology, Hepatology and Nutrition and is an internationally recognized investigator in the area of cholestatic liver diseases. He is a native of Pittsburgh and received his MD degree from the University of Pittsburgh School of Medicine and completed his residency in Pediatrics at UPMC Children's Hospital of Pittsburgh. He completed a fellowship in Pediatric Gastroenterology, Hepatology and Nutrition at the University of Colorado and is board certified in Pediatric Gastroenterology. Dr. Feranchak was a faculty member at UT Southwestern Medical Center in Dallas beginning in 2004 and served as Division Director of Pediatric Gastroenterology there from 2011 until 2017 when he returned to Pittsburgh.

Dr. Feranchak's own NIH-funded research focuses on understanding the basic mechanisms of bile formation, which may serve as the basis for therapeutic strategies for the treatment of cholestatic liver disorders. He has aurthored significant publications in the field and has served on the editorial board for several leading journals, including the Journal of Pediatric Gastroenterology and Nutrition and Hepatology. He has lectured extensively and served in numerous academic leadership positions including the Society of Pediatric Gastroenterology, Hepatology, and Nutrition (NASPHGAN), the American Association for the Study of Liver Dieseases (AASLD), and the Society for Pediatric Research (SPR).
