David Wang, M.D., Ph.D.
Associate Professor

Dr. Wang received his B.A. degree from Asbury College and his M.D. degree from Vanderbilt University.  During medical school, he spent a year at the National Cancer Institute as an HHMI-NIH Research Scholar working in the laboratory of Dr. Robert Lechleider and Dr. Anita Roberts where he investigated TGF-beta and BMP signal transduction.  Dr. Wang then completed residency training on the Osler Medical Service of the Johns Hopkins Hospital and fellowship training in medical oncology at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins.  At the conclusion of his postdoctoral training in the laboratory of Dr. D. Neil Watkins, he received his Ph.D. degree in Cellular and Molecular Medicine from the Johns Hopkins University.  His dissertation research examined the role of Hedgehog signaling in Barrett’s esophagus and esophageal adenocarcinoma.  Dr. Wang’s laboratory is focused on understanding the role of aberrant developmental pathway signaling in esophageal cancer and precursor lesions.  In his clinic, Dr. Wang sees patients with esophageal cancer, gastric cancer, and other gastrointestinal malignancies.
