I am a fifth-year Ph.D. student in the Department of Computer Science and Technology, Tsinghua University, fortunate to be advised by Prof. Dan Li. I am also collaborating closely with Prof. Li Chen and Dr. Kaihui Gao. My research interests lie primarily in AI for networking and AI infra. Currently, I am focusing on building up simulators for LLM training sytems. To date, I have published two first-author papers in top-tier computer network venues, including USENIX NSDI and ACM SIGCOMM. Previously, I received my B.S. in Automation and M.S. in Computer Science, respectively, from Xiangtan University, where I was fortunate to be advised by Prof. Zhetao Li.
