I am a professor of the department of mathematics, School of Science, Beijing Jiaotong University. I got my ph.D in 1994 from the Institute of Mathematics, the Chinese Academy of Science. My research interest is differential geometry.

I was supported by a Grant of National Natural Science Foundation of China.

I visited McMaster University, Canada and New York University, USA respectively for one year as a visiting scholar. I have been teaching Calculus in Chinese for about 20 years and in English for more than 10 years. I won a teaching award of Beijing Jiaotong University in 2012.

Differential geometry

I once hold a project of National Natural Science Foundation of China
