Dr. Fan received his MD degree from Qingdao University Medical College in 1991. He subsequently took an M.S. in Biochemistry and Molecular Biology at the very prestigious Beijing University Medical College, and then he immigrated to US and completed another M.S. degree in Chemistry from the University of Nebraska at Lincoln. He was appointed as a faculty in Liver Diseases Division of Mount Sinai School of Medicine in New York from 2000 to 2002. He then went to Weill Medical College of Cornell University at the Brooklyn Hospital Center, completed his internship and residency. Currently, he is a senior gastroenterology fellow at UTMB.

1. Dr. Fan’s initial research involved telomere length regulation during aging process and telomerase activation in cancer cells. Then he went on and studied the metabolism and disposition of long chain free fatty acids and its relation to the development of obesity and non-insulin dependent diabetes mellitus, as well as the various aspects of hepatic function and hepatic disease. His current research interest is changes in intesinal permeability in patients with Crohn’s disease as well as changes in cytokines and growth factors and enteric glial cells in IBD.
