Research Field: Epigenetic regulation in cancer and regeneration

PERSONAL INTRODUCTION

EDUCATION

  • B.S. in Biology, Shandong University, China

  • Ph.D. in Cell biology, Shanghai Jiao Tong University School of Medicine, China

PROFESSIONAL EXPERIENCE

  • Research Assistant, Department of Pathology, Eastern Hepatobiliary Surgery Hospital, China

  • Research Assistant, Institute of Chinese Medicine, The Chinese University of Hong Kong

  • Postdoctoral Fellow, Children’s Research Institute, UT Southwestern Medical Center, USA

  • Principal Investigator, 2019-current, Department of Biochemistry and Molecular Cell

  • Biology, Shanghai Jiao Tong University School of Medicine, China

RESEARCH INTERESTS

  • Epigenetic regulation influences cell fate by controlling global gene expression in various cellular processes. On the other hand, epigenetic factors are also found to be mutated in many types of cancers. Our lab is interested in understanding the mechanisms how epigenetic factors regulate cell behavior and tissue regeneration under chronic injury. We also focus on how epigenetic dysfunction leads to cancer initiation and development. The long-term goal of our lab is to improve tissue regeneration while prevent cancer through epigenetic regulation.
