I am currently a Research Fellow at the School of Computing, National University of Singapore. I obtained my Ph.D. in computer science from Nanyang Technological University, advised by Prof. Xiaokui XIAO and Prof. Sourav Saha Bhowmick. I received my B.E. degree from Beijing University of Posts and Telecommunications. Broadly speaking, my research aims to develop efficient algorithms for big data using sampling, sketching, or indexing techniques.


  • Jan 14, 2022: One paper “Efficient and Effective Similarity Search over Bipartite Graphs” has been accepted by TheWebConf 2022
  • Dec 14, 2021: One paper “Scalable and Effective Bipartite Network Embedding” has been accepted by SIGMOD 2022
  • Aug 09, 2021: Our paper titled “Scaling Attributed Network Embedding to Massive Graphs” was selected as the best research paper in VLDB 2021

Research Interests

  • Data management and analytics
    • similarity search in graph data
  • Graph mining and learning
    • community detection and network embedding

I welcome enquiries on potential collaborations on interesting topics. Note that, in the papers, every coauthor needs to make substantial contributions to qualify him/her for authorship and the order of authors in the byline reflects the magnitude of contribution.
