About Me
I joined Sony@Tokyo in October 2023. 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.
