Biography

I am currently a final 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, B.A. in Japanese from Dalian University of Technology (DUT) in 2019.

Research Interests

I am intersted in graph representation learning. More precisely, my research focuses include:

  • Node Embedding
  • Graph Neural Networks
  • Social Recommendation
  • Geometric Deep Learning
