I am an assistant professor in the John Hopcroft Center for Computer Science at Shanghai Jiao Tong University.
I was awarded the Ph.D degree in Computer Science by the University of Oxford in 2020, where I was supervised by Prof. Leslie Ann Goldberg and Prof. Andreas Galanis. I was a member of St. Hugh's College at Oxford, and also a Clarendon Scholar, fully-funded by the Clarendon scholarship from 2015 to 2019. Before coming to Oxford, I obtained my bachelor degree in Computer Science from Zhiyuan College at Shanghai Jiao Tong University in China.
I am interested in many aspects of theoretical computer science, discrete probability and combinatorics. Currently I mainly work on designing and analysing approximation algorithms for counting and sampling problems.
2011 - 2015 B.Sc. in Computer Science, Zhiyuan College, Shanghai Jiao Tong University
2015 - 2020 Ph.D. in Computer Science, University of Oxford
