About me

I'm currently a Research Assistant Professor jointly affiliated with the Department of Computing and the Institute for Higher Education Research and Development (IHERD) at The Hong Kong Polytechnic University. Before joining PolyU, I was an Associate Research Professor and a Research Assistant Professor at Zhongguancun Laboratory. I received my Ph.D. degree from the Department of Computer Science and Technology, Tsinghua University, in 2023, advised by Prof. Mingwei Xu. I received my B.Eng. degree from the Department of Electronic Engineering at Tsinghua University in 2018. In Summer 2019, I was fortunate to visit University of Surrey and worked with Prof. Ning Wang at 5G Innovation Centre.

Research

My current research interests span AI for education and computer networks, with a focus on AI-empowered teaching and learning, transport protocols, routing security, and low-latency networked systems.
