I’m currently working at Beihang University ZeusNet Lab. Before that, I received my Ph.D. from Tsinghua University in June 2022, under the supervision of Prof. Fengyuan Ren. From Sep. 2019 to Oct. 2020, I was a visiting student at the Department of Computer Sciences in the University of Wisconsin-Madison, under the supervison of Prof. Aditya Akella.
