Introduction:
From 1993, he joined Prof.Yiqiu Wang's group and began to establish the Laser Cooling and Trapping Lab. in Peking University with the group members. In 1996, he achieved the first MOT in China with his colleagues, and from 1998, he led a group to start the research of semiconductor laser frequency standard at 630nm. From 2001, he began to lead the experiment of Bose-Einstein Condensation and his group achieved BEC in March, 2004 and achieved atom laser of Rubidium in Jan. 2005 respectively. From 2002 his group started experiments of slow light and light storage in EIT medium and from 2003 he started building up femtosecond comb generator for precision measurement. Now he is involving cold atom physics, diode laser frequency standard, precision measurement based on phase locked femtosecond laser and CPT clock. Up to now, he published over 100 papers in journals and conferences. He is a fellow of Quantum Optics Devision, Chinese Association of Physics and a fellow of Chinese Association of Metrology and Measurement.Nonequilibrium statistical physics; nonlinear plasma physics.

Research Interests:
Bose-Einstein Condensation, Femtosecond Optical Comb and Optical Frequency Standard, CPT clock.
