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.

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.
