Bio

I am a Postdoctoral Researcher at the National University of Singapore (NUS), advised by Prof. Jialin Li.. Before that, I received my Ph.D. from Peking University in June 2025, under the supervision of Prof. Qun Huang. I got my M.S. degree in Computer Architecture from Institute of Computing Technology, Chinese Academy of Sciences (ICT-CAS) in 2020, advised by Prof. Qun Huang and Prof. Yungang Bao. My research mainly focuses on network measurement, programmable network, and high-performance network.
