I am now professor and doctoral supervisor at School of Astronomy and Space Science, Nanjing University. I am also one of the deputy director of the astrometry commission, Chinese Astronomical Society. I visited SYTRE at Paris observatory as a joint PhD student from 2011.9 to 2012.9, and received PhD degree in astronomy in 2012. I received the “Excellent PhD Thesis of Nanjing University award” in 2013. In 2017, I was a visiting scholar at the Mullard Space Science Laboratory (UCL, London). My research interest include fundamental theories for astrometry, astronomical reference frames, Earth’s rotation models, and application of VLBI and Gaia data et al. I have published more than 30 scientific papers in major SCI journals for astronomy. I am editor board member of Journal <Progress in Astronomy> since 2023 and <Acta Astronomica Sinica> since 2020.
