About me

I am an Assistant Researcher at IDEA, working with Yu LI and Zijing Liu. Prior to that, I received my master’s degree from Tsinghua University in 2023, co-advised by Xi Xiao and Shu-Tao Xia. My research interests focus on, but not limited to graph/hypergraph neural networks and machine learning. These days I am interested in diffusion models, AI4Science, and drug discovery. Feel free to contact me if you are interested in my research.
