About

I am a PhD Candidate in the School of Cyberspace at Hangzhou Dianzi University, advised by Prof. Pengfei Jiao. I received my M.S. in Computer Science and Technology from Hangzhou Dianzi University (2024) and my B.S. in Computer Science and Technology from Shihezi University (2021).

My research focuses on Graph Learning, with particular interest in Dynamic Heterogeneous Graphs and Foundation Models for graph-structured temporal data.
