Welcome to my homepage!

Shortbio

I am working in Data Management & Analytics Lab, NTU, as a research fellow. I obtained my PhD in computer science from Nanyang Technological University, under the supervision of Professor Gao Cong. I obtained my Bachelor degree from the School of Computer Science and Engineering, Beihang University, China, under the supervision of Professor Shuai Ma.

Research Interests

My main research interests include spatial database management and graph database. I am particularly interested in

  • Querying geo-tagged stream
  • Spatial data visualization
  • Efficient processing of spatial queries
  • Graph and social data analysis
