About Me

I am a final-year PhD student in Computer Science and Engineering, University of Michigan, advised by Prof. Mosharaf Chowdhury and Prof. Harsha V. Madhyastha, and was a visiting researcher at Meta AI. I got my B.S. degree in Computer Science from Shanghai Jiao Tong University in 2017.

Research Interests: Machine learning systems, big data analytics, and networked systems

I develop systems support across different layers of the software stack for efficient datacenter-scale and wide-area computing, including deep learning systems for the cloud, and distributed systems for fast federated computation over the Internet.
