Faculty and Staff

Dr. Yonathan Fuchs is a board certified pediatric transplant hepatologist at Yale New Haven Children’s Hospital. The focus of his practice shifted from pediatric gastroenterology to liver disease at the midpoint of his career. “The challenges and rewards of transplant hepatology are so unique. I love being a child advocate as well as a member of a multidisciplinary team that can transform a child’s life at a critical time. The greatest reward is seeing a kid being a kid again so soon after transplant.”   Dr. Fuchs received his medical degree from Tel Aviv University in Israel. He completed his pediatric residency training at Nicklaus Children’s Hospital in Miami and fellowship in pediatric gastroenterology at Cohen Children’s Medical Center in New York. His interest in liver disease and immunology led him to Stanford University in California where he completed a fellowship in transplant hepatology. Dr. Fuchs is a recipient of the CF Foundation's prestigious Developing Innovative Gastroenterology Specialty Training (DIGEST) award. His current research focuses on better understanding how cystic fibrosis transmembrane conductance regulator enhancers modulate CF-related liver disease. He is collaborating with Yale's CF center in order to establish a protocol that leads to early detection of CF liver disease via biomarkers and advanced imaging. Dr. Fuchs is collaborating with Dr. Michael Schilsky at Yale University on the Wilson Disease (WD) Registry. Yale is one of several WD Centers of Excellence that aims to learn more about the spectrum of WD from infancy to adulthood.
