Dr. Zheng is one of the lead researchers on a project to use immunized sera from vaccinated patients to identify candidate pancreatic cancer associated proteins against which the immune system has been activated. Through this project, he has identified a molecular pathway that underlies the tumor-stroma interaction in the tumor''s microenvironment of pancreatic cancer. His current research interest is to further explore the roles of the pancreatic tumor''s microenvironment in developing immune tolerance and in supporting tumor growth, invasion and metastasis. His long-term goal is to develop novel therapeutics for pancreatic cancer by targeting tumor''s microenvironment and to conduct innovative "first in human" clinical trials.
He is also the lead investigator on the development of vaccines and immune based therapies as pre-operative, post-operative, and long-term maintenance treatments for patients with pancreatic cancer. His clinical research interest is focused on developing multidisciplinary therapeutics in the pre-operative/neoadjuvant setting for patients with pancreatic cancer.
Dr. Zheng is also one of the lead investigators on the development of vaccine-based therapies in combination with surgery and chemotherapy for patients with colorectal cancer.
