About Me

This is William. I am a first year Ph.D. student at UC Berkeley working with Prof. Ion Stoica and with Prof. Rishabh Iyer. I am co-affiliated with Sky Computing and NetSys Lab. I earned my Bachelor degree at University of Illinois at Urbana-Champaign(B.S. in Computer Science and Statistics, Minor in Mathematics).

My current research focuses on LLM inference and GPU communication.

Before Ph.D. I interned at Microsoft Research Asia working on AI Systems. At UIUC, I work closely with Prof. Deepak Vasisht and Prof. Ramesh Sitaraman on space networks and content delivery, and Prof. Tianyin Xu on cloud systems. I also work with Francis Yan and Prof. Ravi Netravali on real-time communications and ML inference infrastructures.
