I am a trained interventional endoscopist who performs invasive pancreatico-biliary procedures. I serve as the Acting Director of Endoscopy at New York-Presbyterian Hospital/Columbia and the Acting Clinical Chief of the Division of Digestive and Liver Diseases. With a gift from the Diller von Furstenberg Family Foundation, I established the Pancreatitis Program at New York-Presbyterian Hospital/Columbia. My research interests include the study of Barrett’s esophagus, pancreaticobiliary diseases, and endoscopic techniques. I am currently a site PI on an NIH funded study using a catheter-based optical coherence tomography imaging system in Barrett’s esophagus.
