Hornor and Award

  • Fellow of the Royal Astronomical Society (FRAS, since 2011)
  • Member of the European Astronomical Society (since 2019)
  • 2009 Chinese Government Award for Outstanding Self-financed Students Abroad (CCTV News: TV, YouTube)
  • Research Interests

    1. Characterization of L subdwarfs: discovery, classification, atmospheric and population properties (Primeval - I; Primeval - IV; Zhang+18c; Primeval - V).
    2. Search for the most metal-poor very low-mass stars and brown dwarfs in our Galaxy (Primeval - II, Press release; Primeval - III; Primeval - VI).
    3. Revealing the physical properties of brown dwarfs with benchmarks in binary systems (Primeval - VII; Zhang+13; Zhang+10, Press release; Pavlenko+15).
    4. Discovery and characterization of ultracool dwarfs in large area surveys (Zhang+09; Burningham+10; Day-Jones+13).

  • About Me

    I joined the School of Astronomy and Space Science at the Nanjing University as a faculty member in September 2019. I was a PSL fellow at the GEPI department of the Observatoire de Paris in Meudon from 2017 to 2019. I was an IAC fellow at the Instituto de Astrofisica de Canarias in Tenerife of Spain from 2013 to 2016. I did my PhD in astrophysics and worked as a researcher at the Centre for Astrophysics Research of the University of Hertfordshire in the UK between 2008 and 2013. I did my MSc in astrophysics at the Yunnan Observatories of the Chinese Academy of Sciences from 2005 to 2008. I obtained a BSc in physics at the Yantai University in 2000-2004. I was born and raised in Tai'an of Shandong province, China.

    News

    I am organizing a 2-days symposium (S12) on the next European Week of Astronomy and Spece Science (EWASS 2019) which will be held in Lyon, France on 24-28 June 2019. Welcome to join us in Lyon to discuss the science and future researches of brown dwarfs.
