About Me

I joined Sony Group Corporation (SGC) in Tokyo in October 2023, with a concurrent role at Sony Interactive Entertainment (SIE). Before that, I held a Ph.D. degree from the Department of Computer Science and Technology at Tsinghua University, where I was advised by Prof. Lifeng Sun . My research has centered on multimedia network streaming, which encompasses topics such as adaptive video streaming, real-time streaming, congestion control, and federated learning.
