Professional title:Professor

Office No.:+86-010-51688453


Since 2003, I have been working in Beijing Jiaotong university as a full professor.

As a visiting scholar, I visited many universities in the global scale and made joint works with my collaborators in the Maryland University, the Johns Hopkins University, the Texas University at Arlington, the California University at Irvine, and the University of Tokyo and so on. I have published more than 50 papers in peer-reviewed international journals cooperated with my colleagues and my students. As a supervisor, more than 6 PhD students have been graduated from this university, and more than 20 graduate students got their Master degree.

Professional Experience

In 2001 I got my PhD at the Institute of Mathematics of the Chinese Academy of Science. From 2005/12-2007/08, as a postdoc at Universidad de Rey Juan Carlos, Madrid,Spain.

Research Field

My research interests focus on bifurcation and chaos of nonlinear dynamical system. Recent years, I focus on the research on the neuron, neuron network, some applications in neurological disease, and hunting motion of high speed vehicles.


As a principle investigator of two projects of National Natural Science Foundation and a project of Beijing Nature Science Foundation.
