I fortunately joined the CS Ph.D. program at UC Berkeley Sky Computing Lab in the fall, 2020. I am currently working with Prof. Ion Stoica on efficient deep learning and system.

I am now focusing on building SkyPilot, a framework for easily and cost effectively running ML and batch jobs on any cloud, which aims to realize the sky computing vision. Please check out our system on Github. The paper will be available soon in NSDI’23.

Before coming to Berkeley, I was an undergraduate student majoring in computer science at Shanghai Jiao Tong University (SJTU), a member of the SJTU ACM Honors Class, and a research intern working with Prof. Kai Yu and Prof. Yanmin Qian at SJTU SpeechLab. I also had a wonderful time as a research assistant working with Prof. Song Han at MIT HAN Lab.
