About

I was born in 1969, Yiwu Zhejiang Province, PRC. In 1991, I got my BS degree from the department of physics, Hangzhou University. Two years later, I went to Peking University majoring astrophysics for Master degree for the following 3 years. In 1999, I received my PhD degree from Shanghai Astronomical Observatory (SHAO), and then became a member of SHAO till now. In the meantime, I visited Purdue Universtiy from 2006 to 2007 as a visiting scholar. From 2013 year, I became a research professor in SHAO.

In current, I mainly focus on the study of the following fields, including the study of active galactic nuclei by using vlbi technique, the physical origin of fast radio bursts, and begin to the study of the epoch of reionization with SKA.

Research Areas

High resolution study of active galactic nuclei, including the formation, acceleration and collimation of the relativistic jet with VLBI; the origin of fast radio bursts; VLBI study of AGN at very high frequency; Investigation of the epoch of reionization with SKA.
