About me

GRAPH & HYPERGRAPH LEARNING

I am a Ph.D. student in Computer Science and Technology at Zhejiang Normal University (ZJNU), advised by Prof. Yunliang Jiang. I am also a visiting Ph.D. student at Nanyang Technological University (NTU), Singapore, working with Assoc. Prof. Kelin Xia. I received my B.S. in Computer Science and Technology from ZJNU in 2023.

My research focuses on reliable learning on graphs and hypergraphs. I study how models detect out-of-distribution data, generalize under distribution shifts, and respond to adversarial changes in relational structure.
