Sam Wang, M.D., FACS is a surgeon-scientist and a member of the Division of Surgical Oncology in the Department of Surgery. His clinical focus includes cancers of the liver, pancreas, stomach, and bile duct.

Dr. Wang graduated from Stanford University, where he received a B.S. with honors in biological science and an A.B. with high honors in history. He attended medical school at Duke University School of Medicine and completed an internship and residency in general surgery at the University of California, San Francisco. He then received advanced training in complex general surgical oncology through a fellowship at Memorial Sloan Kettering Cancer Center. He joined the UT Southwestern faculty in 2014.

In the lab, Dr. Wang is studying cellular intrinsic and extrinsic factors that regulate gastric cancer initiation, progression, and response to therapy. In addition, he is studying the molecular mechanisms behind outcome disparities that Hispanic gastric cancer patients face. The goals for his research are to identify new diagnostic and therapeutic strategies to improve outcomes for cancer patients.

Dr. Wang is a UT Southwestern Disease-Oriented Clinical Scholar and received an R37 NCI MERIT Award for Early-Stage Investigators from the National Cancer Institute. He is a member of the Society of Surgical Oncology, the Association for Academic Surgery, the Society of University Surgeons, the American Association for Cancer Research, and the American College of Surgeons. He is fluent in Mandarin.
