Before moving back to China, I was a postdoc at the Université Paris-Sud (2014 - 2015). I finished my Ph. D. in LRI, Université Paris-Sud (2011 - 2014) under the supervision of Prof. Hao Li. I finished my B. S. and M. S. in the University of Science and Technology of China (2004 - 2011) under the supervision of Prof. Jun-Ming Xu.
