Research Interests The immunotherapy is extremely attractive to clinic physicians as well as to the patients who are suffering from incurable cancers and autoimmune diseases due to its specific targeting and less side affects. The pathogenesis and immunogenesis are the fundamental accesses to address the targets for the specific immunotherapy. My research interests are the pathogenesis and immunogenesis of various cancers and autoimmune related diseases, and the design and development of immunotherapeutics for those resistant to the conventional treatments. Both in vitro and in vivo models are the substantial approaches in my studies
