Dr. Buxbaum brings a clinical and research interest in advanced endoscopic topics to the University of Southern California. His research interests include the development of biomarkers for and the endoscopic management of pancreatic neoplasms. He also has a special interest in complex biliary problems including recurrent pyogenic cholangitis and post liver transplant strictures.

Dr. Buxbaum earned his medical degree from University of California, San Francisco, then went on to complete two fellowships also at UCSF, one in gastroenterology and the other in advanced endoscopy.
