About

I am a PhD Candidate in the School of Cyberspace at Hangzhou Dianzi University, advised by Prof. Pengfei Jiao. I am currently a Visiting Ph.D. Researcher at the National University of Singapore, supervised by Prof. See-Kiong Ng. Previously, I was a Visiting Ph.D. Researcher at the University of Sydney, supervised by Prof. Jie Yin. My research focuses on Graph Learning, with particular interest in Dynamic Heterogeneous Graphs and Foundation Models for graph-structured temporal data.
