Dr. Bruce Wang is a liver specialist who cares for patients with porphyrias, a group of rare genetic diseases in which illness results from a buildup in the body of porphyrins. (Porphyrins are compounds important to producing heme, which is part of metabolic enzymes in the liver and hemoglobin, the protein on red blood cells that carries oxygen.) He runs the UCSF Porphyria Center, the main referral center for porphyria patients on the West Coast. He also cares for patients with other genetic liver diseases, including hemochromatosis, Wilson disease, progressive familial intrahepatic cholestasis, primary biliary cirrhosis and primary sclerosing cholangitis.

Wang conducts clinical research on the porphyrias, including clinical trials for new treatments for the condition. He also conducts basic science research on the liver. His laboratory studies how the different cell types in the liver are developed, patterned and maintained during adulthood, and how they regenerate after injury. He aims to improve the understanding of how liver diseases occur in order to develop new treatment methods.

Wang earned his medical degree from UCSF, where he also completed a residency in internal medicine and a fellowship in gastroenterology. He completed additional training in developmental biology at Stanford University School of Medicine.

Wang is a member of the American Association for the Study of Liver Diseases and American Gastroenterological Association.

    I was so impressed with the quality of attention from Dr. Wang for my case. He had taken the time to review 6 years' worth of my blood tests before our visit, and came prepared with individualized recommendations. I have already told so many people about this: I wish all of my doctors were so thorough!

    Dr. Bruce Wang is awesome.. His staff needs some work with soft skills and general etiquette though but besides that, I love this doctor.. He was very detailed and was able to figure out what was going on with my health after months of seeing a few other doctors

    Dr. Wang was thoroughly prepared for my visit. His background knowledge of my social and medical history was comprehensive in both breadth and depth. He was sympathetic and compassionate during the entirety of the visit (60 minutes). He displayed an excellent grasp of my medical condition (Chronic Hep B) and was able to quickly and expertly address my questions and concerns with confidence and authority. I am looking forward to receiving continuing medical care from this knowledgeable and humane doctor.
