I am a professor and PhD supervisor at the School of Astronomy and Space Science, Nanjing University. I also serve as a deputy director of the Astrometry Commission of the Chinese Astronomical Society and as a member of the editorial board of Acta Astronomica Sinica.

From September 2011 to September 2012, I participated in a joint PhD training programme at SYRTE, Paris Observatory. I received my PhD in Astronomy from Nanjing University in 2012 and the university’s Excellent Doctoral Dissertation Award in 2013. In 2017, I was a visiting scholar at the Mullard Space Science Laboratory, University College London.

My research focuses on the theoretical foundations of astrometry, astronomical reference frames, Earth rotation models, and applications of VLBI and Gaia data. I have published more than 20 papers in major SCI-indexed astronomy journals.
