Timothy Cragin Wang, MD

Gastroenterology (Board Certified, Primary Specialty)
Internal Medicine (Board Certified)
Cancer Care
One of America's Top Doctors


Dr. Timothy Wang is a leading expert in gastroenterology cancer research and patient care. His research specifically focuses on transgenic/ knockout mice, stem cells, lineage tracing, bone marrow-derived cells, and FACS analysis of immune/epithelial cells in the gut. His laboratory has for decades investigated the molecular mechanisms of gastrointestinal carcinogenesis, and has been continuously funded by the NIH for 29 years and by the NCI for 14 years. His lab has worked for many years on the role of inflammation in promoting gastrointestinal neoplasia, including colon cancer. His research has defined key roles for stromal cells in tumor development, including myeloid cells.

Dr. Wang is the GI Division Chief at Columbia and serves as Co-leader of the Tumor Biology and Microenvironment Program of the Herbert Irving Comprehensive Cancer Center. He also serves as director of the Columbia University NCI U54 Tumor Microenvironment (TMEN) program and directs the Barrett’s Esophageal Translational Research Network (BETRNet) program and the Intestinal Stem Cell Consortium (ISCC) at Columbia.

In addition to his leadership at Columbia, Dr. Wang has served as President of the American Gastroenterology Association (AGA). His work has been recognized with numerous awards, including the Outstanding Investigator Award from the NCI, the Irene and Arthur Fishberg Prize for medical research, the Ruth Leff Siegel Award for pancreatic cancer research, and the William Beaumont Prize in Gastroenterology from the AGA. Over his career, he has organized numerous conferences, including conferences on Gastrin, Regulatory Peptides, AACR Symposium on Gastric Cancer, Tumor Microenvironment, and Keystone Conferences.
