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 at Tsinghua University. I am now also a research intern at KAUST, advised by Prof. Mohamed Elhoseiny.

My research interests include:

• Enhancing the robustness, scalability, and interpretability of graph neural networks.
• Pioneering innovations to accelerate large language model prediction.
