I have been working on moving object databases for years. Applications related to moving objects (e.g. vehicles, users of wireless devices) have become more and more popular attributed to the advances in positioning technologies such as GPS and rapid developments of wireless communication devices. Such applications contain a large amount of frequently updated moving objects which cannot be well supported by the traditional databases. In order to efficiently manage moving objects, I have proposed several moving object indexing and querying techniques. Recently, I am also interested in the topic of location privacy protection which aims to protect users’ location information from being disclosed to unauthorized parties. 

Information security is always a big concern in many applications. My other research interest lies in developing tools for managing and analyzing access control policies in the scenario of distributed applications like grid computing, content distribution networks, and the cloud.

My research in one area has helped me find new research problems in other areas, and inspired new approaches.
