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