I am currently an Assistant Researcher at Zhongguancun Laboratory, collaborating closely with Dr. Li Chen and Prof. Dan Li. I received my Ph.D. in Department of Computer Science and Technology, Tsinghua University, in 2023, under the supervision of Prof. Dan Li.
I have broad interest in networking and systems, including Digital Twin Networks, Programmable Networks, Intelligent Networks, etc. Currently, I am focusing on constructing digital twins of networks, including DCNs, Internet.
