I am currently a full research professor at National Astronomical Observatory of China (NAOC), which is located in Beijing, starting from 2012. Meanwhile, I am also staying as the long-term collaborator with Harvard-Smithsonian Center for Astrophysics at Cambridge, MA, USA, where I spent five years as a postdoctoral fellow out there before I moved back.

I joined NAOC through the “Thousand Young Talent Program” which is sponsored by Chinese government and I won the award in 2012, and am affiliated with the Galactic and Cosmological division at NAOC.

I am building a group on stellar-mass black holes and their related high-energy astrophysics. Graduates and all level researchers who are interested are welcome to join and contact us.

During my stay at CfA, I worked with Jeffrey McClintock and Ramesh Narayan on measuring the spin values for the stellar-mass black holes in our and neighbouring galaxies. 

I obtained my PhD degree on Astronomy and Astrophysics from Penn State University.  My thesis advisor was Peter Meszaros. The research subject then was about the high-redshift Gamma-ray Bursts (GRBs) and their detectability.

My bachelor and master degree were both endowed by Nanjing University, and my master thesis advisor was Zi-Gao Dai.

We recently finished a series of work on Cygnus X-1, which is the first black hole candidate ever, and here is the news release on Cygnus X-1 paper from Chandra X-ray Center/CfA  and NRAO. The spin paper was selected as the Picture of the Week by HEASARC.
