Biography

I am currently a Postdoc Researcher at the Department of Machine Learning, Mohamed bin Zayed University of Artificial Intelligence (MBZUAI), working with Prof. Le Song. I also work closely with Dr. Shahin Mohammadi at GenBio AI. I obtained my Ph.D. at the Department of Systems Engineering and Engineering Management (SEEM), The Chinese University of Hong Kong (CUHK) in 2024, under the supervion of 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 and AI for Science. More precisely, my research focuses include:

  • Graph Representation Learning
  • Recommendation
  • Anomaly Detection
  • Antibody Design
  • Single-cell Perturbation

I am looking for collaboration. Please email me if you are interested :)
