Welcome to my homepage!

I am a senior undergraduate student in Department of Software, Tsinghua University. I am currently working on the research of graph mining under the supervision of Prof. Hanghang Tong at University of Illinois at Urbana-Champaign. Before that, I worked under the supervision of Prof. Quanming Yao and Prof. Zhenan Sun. I am now also a research intern at KAUST, advised by Prof. Mohamed Elhoseiny.

I will begin my Ph.D. at the University of Illinois at Urbana-Champaign in Fall 2025, fortunate to be supervised by Prof. Hanghang Tong.

My research interests include Multi-modal Learning, Efficient Deep Learning, and Graph Learning.
