I am leading the DEEP Lab at The Hong Kong Polytechnic University (Data Exploring and Extracting @ PolyU). We strive to develop effective machine learning algorithms for networked data to solve real-world prediction problems in social science, recommender systems, education, transportation, healthcare. DEEP Lab has 12 Ph.D. students, 1 postdoctoral fellow, and several master's students.
[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. My research interests span graph neural networks, knowledge graphs, attributed networks, anomaly detection, recommender systems, and question answering.
