Short Bio

I am an Assistant Professor at CSE at Concordia University since June 2008. Before joining Concordia, I was an Associate Researcher Officer in the Institute for Information Technology (IIT) in the National Research Council's (NRC) since Feb. 2003. I am an Adjunct Professor in the Faculty of Computer Science in the University of New Brunswick since 2004. I obtained my Ph.D. from Tsinghua University (China) in 1999 from a joint DAAD program with the University of Leipzig, Germany. I worked in the University of Toronto and the University of Paris 13 as a post-doc and one year in US as a software engineer druing Sept. 1999 to Feb. 2003. Currently, I am working on two topics:

1) Web service modeling and computing
I am using formal models, such as automaton, process algebra and Petri net, to model Web service networks, and investigating computing algorithms for Web service monitoring, diagnosis and reconfiguration.

2) Monotonicity analysis in model abstraction and data mining
This is a problem I identified when I study qualitative model abstraction. Qualitative model is a kind of symbolic model used for model-based reasoning, or more generally, automatic reasoning. I study how to build the qualitative model from numerical data. The concept of scale-based monotonicity is developed in 2004. Now I am investigating the potentials of using it for feature points detection, knowledge representation and data mining.
