I am a medical oncologist who specializes in the treatment of malignancies of the gastrointestinal tract, including esophageal, stomach, colorectal, and pancreatic cancers. My research focuses on the development of new treatments for patients with esophageal and gastric cancers. I am particularly interested in exploring the combination of chemotherapy and radiation to treat cancers of the esophagus. I am also investigating the role that the immune system plays in controlling cancers of the esophagus and stomach to determine if we can harness the immune system to attack these cancers
