About

I am a PostDoc at UC Berkeley advised by Ion Stoica. I have equal interests in core systems and ML systems research, e.g., efficient LLMs, GPU communication, heterogeneous computing. I am currently working on UCCL for GPU collective communication.

I will be joining UC Davis CS as an Assistant Professor, starting July 2025.

I finished my PhD in Computer Science at Harvard University in 2024, advised by Minlan Yu and James Mickens. I received my B.S. in Computer Science at Peking University in 2018, advised by Tong Yang on probabilistic data structures and streaming algorithms. I was supported by a Google PhD Fellowship in Systems and Networking (see my app materials).
