I joined the Department of Computer Science and Software Engineering in Concordia University in June 2008, after five years as a Researcher Officer in the Institute for Information Technology (IIT) in the National Research Council's (NRC). I am also an Adjunct Professor in the Faculty of Computer Science in University of New Brunswick.
Office Hour in Winter 2010
Monday and Tuesday from 10:30AM to 12:00PM.
Research Topics
Currently, I am working on the following two topics:
1) Web service modeling and computing
I am using formal models, such as automata, 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.
Potential Students
I am looking for a Ph.D. student and a post-doc for a coming project. The ideal background is data ming, Web services, Web service composition, cloud computing, and software engineering.
