Welcome Message from Timothy C. Wang, MD
Dorothy L. and Daniel H. Silberberg Professor of Medicine
Chief, Division of Digestive and Liver Disease

Welcome to the Division of Digestive and Liver Diseases at Columbia University Medical Center, where we strive to achieve excellence in clinical care, teaching and research. The division has a long history of national prominence in gastroenterology and hepatology, and with the recent addition of six new faculty in the past two years, now provides a broad and comprehensive array of clinical services. In addition, the division has a strong and growing base in basic and clinical investigation, and an increasing focus on training fellows in research.

We currently offer comprehensive clinical and research programs in interventional endoscopy, esophageal disease, celiac disease, inflammatory bowel disease IBD), small bowel disorders including SI transplantation, liver disease and transplantation, irritable bowel syndrome, nutrition, pancreatic disorders, and gastrointestinal cancer prevention and treatment.

The Section's nationally and internationally recognized faculty is committed to advancing the science and practice of gastroenterology and hepatology by translating fundamental discoveries in the laboratory into advanced, state-of-the-art patient care. The division is part of New York Presbyterian Hospital, one of the top six hospitals in the country, and is rapidly growing in its reputation, scientific base and clinical volume. The division has established Centers of Excellence in Celiac Disease, Esophageal Disease, Diseases of the Pancreas and NOTES. The Division is home to a diverse base of physician-scientists and is also home to the “Tumor microenvironment program”, and NCI U54 multi-PI program that is focused on the role of stromal cells in gastric and hepatic cancers. The Division of Gastroenterology carries out diverse basic research studies in areas of cancer, stem cells, epigenetics, development, fibrosis, hepatic steatosis, fatty acid transport, and cell biology.  In addition, there is a range of active translational research, including celiac disease, Barrett’s esophagus and esophageal cancer, colorectal cancer and screening, and inflammatory bowel disease.

The primary purpose of the fellowship training program remains one of producing outstanding academicians and clinicians with unparalleled skills in gastroenterology. To accomplish this goal, the first fellowship year is devoted to the basics of clinical gastroenterology, exposing the trainee to a wide variety and large number of common gastrointestinal diseases. The subsequent two years complete clinical core requirements while providing opportunities to develop skills in a basic sciences laboratory or in the arenas of clinical epidemiologic or translational research. An optional fourth year advanced fellowship provides the interested trainee with advanced interventional endoscopy skills for a career in biliary, pancreatic and interventional endoscopy. Approximately 50% of recent fellows from the Division of Gastroenterology are currently making contributions to academic gastroenterology as basic scientists, clinical investigators or educators.
