Research Interests

My interest lies in the experimental particle physics. That is to understand the origin of the world by the experimental probe to the fundamental structure and their interactions of particles. Currently, I am involved in the BESIII project in BEPCII facility in China, and the LHCb project in CERN in Switzerland.
