He is now an Associate Professor at Institute of Computing Technology, Chinese Academy of Sciences.

He spent his one-year sabbatical at Computer Science Department, Carnegie Mellon University (CMU), as a research scholar. He was hosted and supervised by Professor Christos Faloutsos, 2016-2017.

He received his Ph.D. degree from Computer Science & Technology Department, Tsinghua University in 2010, and was funded by hosting Professor Lei He to visit Electronic Engineering Department, University of California, Los Angeles (UCLA) as a Ph.D. student, 2006-2007. He is in consequence listed as one of the Alumni in Academia of Electrical & Computer Engineering, UCLA.

He focuses on research areas such as big graphs and time series analysis, large language models, and scalable algorithm design. His expertise is applied to interpreting complex patterns across diverse domains, including online user behavior within social platforms and e-commerce, as well as various networked systems ranging from academic collaborations, supply chain, financial transactions and biological networks. The featured works are published on IEEE TKDE, ACM TKDD, and proceedings of top-tier conferences such as AAAI, CIKM, WSDM, IJCAI, ECML-PKDD, ICDM, and SDM. Some of the publications are recognized as ASP-DAC 2010 best paper candicate, ECML-PKDD 2020 best student DM paper award.

NEWS

Best student DM paper award is granted by ECML-PKDD 2020 award chairs, on our paper "SpecGreedy: Unified Dense Subgraph Detection". The work proposes a unification of several dense subgraph detection problems which is the heart of anomaly detection, and a fast spectral algorithm, verified on 40 real-world networks and a 1.47-billion-edge graph.
