I am a tenure-track Assistant Professor in the School of Intelligent Software and Engineering at Nanjing University. 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 in the Department of Computer Sciences at the University of Wisconsin-Madison, under the supervision of Prof. Aditya Akella.
