Christopher B. O'Brien, MD is Professor of Clinical Medicine at the University of Miami School of Medicine and Chief of Clinical Hepatology and Research at the Center for Liver Diseases. Dr. O'Brien received his medical degree from The Johns Hopkins University School of Medicine in Baltimore, Maryland. He completed a Fellowship in Hepatology at the University of Miami, and a National Institutes of Health Fellowship in Clinical Nutrition and a Fellowship in Gastroenterology, both at the University of Pennsylvania. Dr O’Brien was Medical Director of Liver Transplant at both the Hospital of the University of Pennsylvania and the Children's Hospital of Philadelphia. He served as Director of Clinical Activities of the Gastrointestinal Section and was Clinical Director of the Liver Center. He was the Director of the Hepatitis Laboratory and ultimately the Acting Chief of the Gastrointestinal Section at the University of Pennsylvania. He has published extensively and is the author of more than 180 abstracts, papers, and book chapters. Finally, Dr. O’Brien’s research credentials are extensive and he has served as the Principal Investigator of more than 80 Phase 1 to Phase 4 clinical trials investigating new treatments for chronic liver disease. As the Science Reviewer for the Center for Liver Diseases, he has been responsible for the overview of 139 research trials at the University of Miami’s Miller School of Medicine.
