About Me

I am a Network Architect and Researcher at Bytedance, working on large-scale AI and datacenter networking. I have received my Ph.D. degree in Computer Architecture from Institute of Computing Technology, Chinese Academy of Sciences (ICT, CAS), advised by Prof. Gaogang Xie and Prof. Quan Yu. Throughout this timeframe, I have conducted research on high-performance data center networking in collaboration with Prof. Zhenyu Li, Prof. Kai Chen and Dr. Layong Luo. Before that, I received my B.Eng in Computer Science in Huazhong University of Science and Technology (HUST) in 2019.
