Dr. Shen is the head and medical director of the IBD Center at Columbia. He is also the Vice Chair for Innovation in Medicine and Surgery and a Professor of Medicine (in Surgery). He is one of the world’s pre-eminent leaders in interventional inflammatory bowel disease (IBD) due to his specialized expertise in treating a wide range of pouch-related disorders. In addition to pouchitis and pouch diseases, Dr. Shen specializes in IBD, GI endoscopy (including endoscopic pouch procedures), and imaging technology. Dr. Shen is known as a pioneer in interventional treatment for IBD - this includes postponing or eliminating the need for surgery in some cases.
