IPADS Laboratory

Shanghai Jiao Tong University

Shanghai, China

I am a PhD student at the Institute of Parallel and Distributed Systems (IPADS), Shanghai Jiao Tong University (SJTU), advised by Prof. Haibo Chen and Prof. Mingkai Dong. I received my B.Eng. degree in Information Engineering from SJTU in 2025.

My research interests primarily focus on MLsys, AI Infrastructure, and Operating Systems. Currently, I am working on optimizing system mismatches in on-device LLM inference and agentic systems.

I am a core contributor to PowerServe, a high-performance LLM inference framework for mobile devices.

I have developed a relatively solid foundation in algorithms and data structures, and was fortunate to receive first prizes in the National Olympiad in Informatics in Provinces (NOIP) for four consecutive years. I will also serve as Chairman of the CCF SJTU Student Chapter starting from Jan 2026.

Outside of research, I really enjoy badminton, and I’m quite skilled at it. I am the member of the SJTU Badminton Team and the captain of the Badminton Team of the School of Electronic Information and Electrical Engineering (SEIEE) at SJTU. I have won many awards in badminton, ranging from amateur competitions to provincial professional youth competitions
