I am currently an Assistant Professor in the Department of Computer Science, Aalborg University. I received my PhD degree from University of Hong Kong in 2012. I received my BSc and MSc degrees from Xi’an Jiaotong University in 2003 and 2006, respectively.

 

Research Interests

Spatial Database, Data Uncertainty, and Data Cleaning.
