About Me

I am a 5th-year PhD student in Computer Science and Engineering, University of Michigan, advised by Prof. Mosharaf Chowdhury and Prof. Harsha V. Madhyastha, and a visiting researcher at Meta AI.

My research is at the intersection of networked systems and machine learning (ML) in the context of data-intensive computing, including big data systems for scale-out ML and federated data analytics.

Prior to Umich, I got my B.S. degree in Computer Science from Shanghai Jiao Tong University in 2017.
