Dr. Fu received his Ph.D. in Immunology at Peking University, China, where he studied the role of chemokines in immune cell migration and maturation. Dr. Fu did his postdoctoral training first at Joslin Diabetes Center and then at the Department of Microbiology and Immunobiology, Harvard Medical School, Boston, where his research has focused on the pathogenesis of autoimmune type 1 diabetes and the molecular mechanisms of Foxp3+ regulatory T cells.


Dr. Fu’s research focuses on the immune regulatory mechanisms that lead to type 1 diabetes with the goal of discovering new preventive and therapeutic strategies.  His lab is also exploring new imaging methods for predicting the risk of developing type 1 diabetes before patients are diagnosed with the disease.
