Early on in her professional career as a Pediatric Gastroenterologist, Dr. Jonas became interested in Hepatology as an academic focus. In great part, this was due to her interaction with the Center for Liver Disease at the University of Miami, and its leaders, Drs. Leon and Eugene Schiff. When Dr. Jonas was presented with the opportunity to return to Boston and develop the Liver Disease program here at Boston Children's Hospital, it proved to be a challenge she could not resist. Her primary research focus has been viral hepatitis in children, but she has also been gratified by watching the general Hepatology and Liver Transplant services grow and flourish over the last 25 years.
