About
I am currently a Ph.D. candidate in Computer Science and Technology, jointly trained by Tongji University (TJU) and The Hong Kong Polytechnic University (PolyU), supervisor by Prof. Jiannong Cao and Prof. Jihong Guan.
Prior to this, I received my B.Sc degrees from Beijing Jiaotong University (BJTU) in Computer Science and Technology (Top 10%). From April 2025 to November 2025, I was a visiting scholar at the University of Illinois Chicago (UIC), advised by Prof. Philip S. Yu.
My research focuses on data mining, graph neural networks, and foundation models. I have published more than 20 papers in total, including 5 first-authored papers.
I am open to research discussions and collaborations. Please feel free to contact me.
