Biography

Dr. Christopher Fan is a clinical and research gastroenterologist interested in understanding the role of the gut microbiome and its interactions with mucosal immunology in disease pathogenesis. During his gastroenterology fellowship, he was also a clinical pharmacology T32 fellow and is interested in elucidating new targets for the treatment of disease processes that are mediated by these interactions. Dr. Fan is a member of the AGA.

Dr. Fan is a Houston native, having graduated from Bellaire High School and Rice University with a BSE in Bioengineering. He subsequently went on to medical school at Duke University where he was also a HHMI Medical Research Fellow at Massachusetts General Hospital/Harvard Medical School. This was followed by internal medicine residency and gastroenterology fellowship at Johns Hopkins. His clinical and research interest focus on immunotherapy related toxicities in the gastrointestinal tract due to cancer treatment, inflammatory bowel disease and general gastroenterology.
