Dr. David Zhen is a medical oncologist who specializes in treating patients with gastrointestinal cancers. His research centers around the development of clinical trials evaluating new therapies and combination approaches for the treatment of patients with gastrointestinal cancers, particularly pancreatic and gastroesophageal cancers. He is also conducting research to understand the interactions of the immune system in gastrointestinal cancers and how this can be manipulated to improve upon the response to immunotherapy drugs called checkpoint inhibitors, which block a braking system that cancers use to tamp down the immune response.
