Biography
I joined the Northwestern Polytechnical University (NWPU) as an associate professor at MIIT Key Laboratory of big data storage and management in November 2022. I was a Postdoctoral Fellow at the University of Hong Kong, working with Prof. Reynold Cheng. I received my Ph.D. degree from the Department of Computer Science at the University of Hong Kong (HKU) in January of 2022, and received M.Eng. degree from Waseda University, and B.Eng. degree from Sichuan University, respectively.
My research interests mainly focus on the areas of data mining and machine learning, particularly spatial-temporal data mining, graph data mining and deep neural networks. Till now, I have published 10 papers in the areas of data mining and database, and most of them were published in top-tier conferences and journals (e.g., PVLDB, ICDE, and SIGMOD). I have served as a reviewer for several top conferences and journals (e.g., CIKM、SIGMOD、SIGIR、Information Sciences, Knowledge and Information Systems, Frontiers of Computer Science, Data Science and Engineering(DSE), and Knowledge-Based Systems(KBS)).
Research Interests
My general research areas are data mining and machine learning. Currently, I am working on the following research topics:
- Spatial-Temporal Data Mining/Urban Computing: trajectory outlier detection, traffic incident detection
- Graph Data Mining/Network Representation: knowledge graph embedding, densest subgraph discovery
- Deep Neural Networks/Graph Neural Networks: graph weight completion, deep generative modeling
