About

Hi! I am Youzhe Liu (刘有哲). Right now, I am a Ph.D. student at University of California, Riverside, advised by Professor Yihan Sun and Yan Gu. I got my B.S. in Data Science from Fudan University.

Research

My current research focuses on designing parallel algorithms, especially graph algorithms, with both theoretical guarantees and practical implementations. I also work on efficient model training and RL training infrastructure.
