I am a CS Ph.D. Candidate at University of Illinois at Urbana-Champaign (UIUC) advised by Prof. Deepak Vasisht, starting from 2020 Fall.

Prior to UIUC, I obtained my B.E. degree in Electronic Engineering and Information Science, from School of the Gifted Young, University of Sciecne and Technology of China (USTC).

My research involves designing practical and robust AI for real-world networked systems.

My research was awarded Qualcomm Innovation Fellowship'22.
