Biography

I am currently a third-year Ph.D. student at the Department of Systems Engineering and Engineering Management, The Chinese University of Hong Kong (CUHK), supervised by Prof. Sibo Wang.

Before that, I obtained my B.E. in Computer Science and Technology from Beihang University in 2021.

Research Interests

I am interested in graph representation learning and data mining. Current topics include:

• Scalable Graph Neural Networks
• Graph Anomaly Detection
• Graph Neural Networks with Large Language Models
