I was graduated from Nankai University under the supervision of Bill Chen at the Center for Combinatorics in 2010. Then I chose to be a postdoc at BICMR in Peking University and a postdoc in University of Haifa in Israel for two years respectively. Since December 2014 I became an associate professor at Beijing Institute of Technology. I have been a visiting scholar at MIT under the supervision of Professor Richard Stanley for the academic year 2018-2019. My research area is algebraic combinatorics, with recent interests the positivity problems of the chromatic symmetric functions of graphs and topics around.
