  • Ph.D. Molecular & Cellular Biology, Ohio University, 1998
  • MS. Animal Science, ChangChun University of Agriculture and Animal Science, 1988

Research Interests

  • Experimental tumor therapy, especially in the area of tumor and tumor microenvironment activated pro-drug therapy. We have been working on modified toxins as well as conditional replicating virus as ways to target tumors.
  • Establishing disease models through transgenic technique and gene knockout.
  • Tumor related kinase inhibitor screening from traditional  medicinal herbs.
