Research Interests

I am interested in problems related to risk analysis, risk-informed planning, and operations research (OR) in general. I am specifically interested in various aspects of fleet mix planning, and how risk analysis can be integrated or adapted to complex OR models.

I work on some of the following sub-problems:

Bin packing, covering and knapsack problems as well as other NP-hard problems
Scheduling
Routing

I usually work with the following types of methods/tools:

Simulation-based optimization
Single Objective and Multiobjective optimization via heuristics (SA, GA, etc.)
Discrete Event and Agent-Based Simulation
Statistics and probability-based
Constructing surrogate models to obtain solutions for huge real-world problems

I am also still interested in any problems related to energy minimization/optimization in image segmentation. See my PhD thesis on Stochastic Nested Aggregation for Images and Random Fields.

Other interests include principal curves, as well as other data mining and data visualization tools.

Looking for Graduate Students

I am looking for graduate students. You need to have funding (NSERC, OGS, etc.) if you are interested to work with me. I would be a co-supervisor together with another professor from the University of Waterloo (e.g., Prof. Fieguth) or from the University of Ottawa (e.g., Prof. Petriu). This is a great opportunity for anyone interested in working on huge real world problems. If you are interested, first please read some of my papers before writing to me.

Professional Activities

I have been very active in the IEEE since 1995. In 2012, I am a member of the IEEE CIS Conference Committee. I was the Vice President for Members Activities of the IEEE Computational Intelligence Society from 2007 to 2010. I have in the past been very active in the IEEE Computer Society, IEEE Region 7 (Canada), and in various local chapters in Kitchener-Waterloo and Ottawa.

I have also been involved in several conferences recently:

2011 IEEE Symposium on CI for Security and Defense Applications (Symposium Chair)
2011 IEEE Symposium Series on Computational Intelligence (Publicity co-Chair)
2010 IEEE Congress on Evolutionary Computation (Program Committee Member and Special Session Organizer)
2010 International Joint Conference on Neural Networks (Program Committee Member)
2010 IEEE Symposium on CI for Security and Defense Applications (IEEE WCCI affiliated workshop)
2010 IEEE International Conference on Computational Intelligence for Measurement Systems and Applications (Program co-Chair)
2009 IEEE Symposium on CI for Security and Defense Applications (General Chair)
2009 IEEE Congress on Evolutionary Computation (Program Committee Member)
2009 International Joint Conference on Neural Networks (Program Committee Member)
