My research covers following areas:

• Secure and flexible Information Sharing in Coalition Environments . I am interested in secure and flexible (situation aware) access control for information sharing in coalition environment.
  
  
• Privacy preserving data mining and data management. I am interested in algorithms for preserving privacy of data and at the same time allows accurate analysis of the data.
  　
• Data Exploration and Navigation. Database users often find it difficult to find useful information from databases. Their queries often return too many irrelevant answers. I am interested in using data mining, navigation, and information retrieval techniques to help user narrow down their scope of search and quickly locate relevant answers.
  　

• Adversarial learning. It is easy for attackers to modify their attacks to evade detection techniques used in cyber security. I am interested in attackers' evasion strategies as well as counter measures that can make detection techniques more robust.

• Efficient and scalable RDF triple store in distributed and resource-constrained environment. RDF is the data format for semantic web. I am interested in developing systems that can store and process large scale RDF data efficiently in distributed and sometimes resource-constrained environment.
