Bio

I am currently a system software engineer at PH, working on system software and infrastructure for AI chips. Before joining PH, I received my Ph.D. in Computer Science and Technology from the Institute of Computing Technology, Chinese Academy of Sciences (ICT-CAS) in June 2026, under the supervision of Prof. Ninghui Sun and Prof. Sa Wang. Prior to my doctoral study, I worked at Huawei's Poincare lab from July 2020 to January 2022. I received my M.S. degree in Computer Architecture from ICT-CAS in July 2020, under the supervision of Prof. Weisong Shi and Prof. Yungang Bao. I received my B.S. degree in Computer Science from Hefei University of Technology in 2017.
