I am leading the DEEP Lab at The Hong Kong Polytechnic University. We strive to develop effective algorithms for networked data to solve real-world prediction problems in social science, recommender systems, education, transportation, healthcare, etc. Our research interests span large language models, knowledge graphs, network analysis, recommender systems, and question answering.
[Open positions] I am actively recruiting Ph.D. students and postdocs (fully funded). Please feel free to drop me emails with your CV. Self-funded visiting students/scholars are welcome.
