Koshi Kunimoto, MD, PhD

Research Manager

Koshi Kunimoto received MD and PhD from Kyoto Prefectural University of Medicine in Japan. He worked as a hepatologist and a gastroenterologist in Kyoto prefectural university hospital for several years. As a basic scientist, he worked on liver regeneration, kidney development, and cilia-related disease including airway diseases. Now his research interest is shifting to more translational research as well as to new drug development of liver diseases such as ASH and NASH. Outside the lab, he enjoys playing tennis with his whole family.

Yuan (Lena) Li, BMed, PhD

Postdoctoral Scholar

Yuan Li received her medical bachelor degree from Huazhong University of Science and Technology in China, and her PhD degree in Toxicology from University of Kansas Medical Center. She is mainly interested in the contribution of NASH to the microenvironment of liver tumorigenesis and metastasis. In her spare time she likes to explore new restaurants in the city.

Weiguo(Jerome) Fan, PhD

Postdoctoral Research Fellow

WeiguoFan’s research focuses on liver diseases. He got his PhD degree in virology and immune response at InstitutPasteur of Shanghai, Chinese Academy of Sciences. The two main projects during his PhD program were: 1) explore the relation between the immune response in Hepatitis C virus infection and Interferon treatment; and 2) investigate the function of ECM1 in liver fibrosis. As a postdoc in Stanford, he will try to integrate basic and translational liver research and focus on: 1) investigate molecular functions of liver immune cells in liver disease; 2) explore key factors determining the change of liver microenvironment that cause liver diseases; 3) use new techniques, such as next-generation sequencing, RNAseqor signal cell sequencing, to explore key factors affecting liver disease and treatment in patients.
