I am a second-year Ph.D. student in UC Berkeley EECS, where I am part of the Sky Computing Lab advised by Prof. Ion Stoica. Before starting my Ph.D., I completed my undergraduate studies in the ACM Honors Class at Shanghai Jiao Tong University. During my senior year, I had a wonderful experience working as a research intern at the Sky Computing Lab as well. Prior to that, I was fortunate to work with Prof. Tianqi Chen at CMU.

My research interests lie in accelerating and optimizing systems for AI applications, particularly in large-scale, multi-region, and multi-cloud environments. I am a core contributor to SkyPilot.
