Hi! Here is Xizheng Wang. I’m currently an Assistant Researcher in Zhongguancun Laboratory, working closely with Prof. Dan Li and Dr. Li Chen(Associate Researcher). Before that, I received my Ph.D. degree in Computer Science from Tsinghua University in 2026 and M.Sc. degree from Hunan University in 2022.
My research interest focuses on large-scale AI infrastructure (e.g., high-performance CCL), and AI for Network.
