I am a professor in School of Software at Shanghai Jiao Tong University and a member of Institute of Parallel And Distributed Systems (IPADS). My research interests include operating systems, computer architecture. Currently, I'm now focusing on hardware-software co-design for better performance and isolation. Some recent projects by my students and colleagues include the Penglai (蓬莱) RISC-V TEE, the XPC architecture extension for fast IPC, the Catalyzer serverless framework with <1ms startup latency, the ServerlessBench test suit for serverless frameworks, and the DeSearch search engine for web3.

In the era of AI, technologies represented by LLM are driving exciting revolutions. During the App era, OSes were designed for human interaction; in the LLM era, OSes will increasingly be operated by large language models (LLMs) rather than by humans. Consequently, both OSes and applications face unprecedented opportunities and challenges. In IPADS, we have proposed the concept of a “Model-Native Operating System” and have already begun new researches, exploring topics including record & replay of AI Agents, memory of AI Agents, new abstractions and interfaces of AI OSes, etc.

I am currently looking for self-motivated students with a good background in computer systems. Please email me if you have interests.
