Assistant Research Professor


  • BS - 1983 - Zoology, Shandong University, China
  • MS - 1986 - Developmental Biology, Shandong University, China 
  • PhD - 1996 - Developmental Biology,  Shandong University, China

Courses Taught

  • Immunology (BIOL 4113/5113)

Research Interests


  • Regulation of autoimmune T cell activation
  • Role of B cells in autoimmune diseases

My research is focused upon understanding how dysfunctional immune cells mediate autoimmune inflammation. More specifically, I am interested in 1) the cytokines secreted by autoreactive T cells that mediate epithelial cell hyperplasia and tissue fibrosis, and 2) the cytokines that are involved in the pathogenesis of atherosclerosis.  The goal of my research is to find novel therapeutic targets for intervention on autoimmune diseases such as autoimmune thyroiditis, rheumatoid arthritis, as well as cardiovascular disease.
