Hi! I’m Junnan Li. I received my B.S. in Computer Science from the University of Wisconsin–Madison, where I was fortunate to work with Prof. Karu Sankaralingam on machine learning for systems.

My interests lie in AI agents and AI infrastructure. I am currently contributing to SGLang-Omni, mainly working on full-duplex streaming and serving performance.
