My research

My initial research interests were in graph theory (with an emphasis on hamiltonian cycles and later on perfect graphs) and in combinatorics (with an emphasis on extremal problems and on random discrete structures). Then they extended to analysis of algorithms (with an emphasis on cutting-plane proofs) and to operations research (with an emphasis on linear programming). Through the 1990s, I was preoccupied by the traveling salesman problem. In the summer of 2009, I began learning about EEG recordings of epileptic seizures. I also have a passive interest in computational neuroscience. Right now I am most interested in two different subjects: the possibility of generalizing the geometrical De Bruijn-Erdős theorem to finite metric spaces and the relationship between pseudorandom number generators and McCulloch-Pitts neural networks.

With my friend Najiba Sbihi, I organized a Séminaire de Mathématiques Supérieures / NATO Advanced Study Institute Combinatorial Optimization: Methods and Applications which took place on 19 -- 30 June 2006 in Montreal. On my own, I organized a workshop Hybrid methods and branching rules in combinatorial optimization, which took place on 18 -- 22 September 2006 in Montreal. At the end of September 2006, I launched ConCoCO (Concordia Computational Combinatorial Optimization) research group; its last session was held on 26 June 2014. In June 2010, I ran a Concordia's summer camp in mathematics and computer science.

Here are my list of publications with a few links to related web pages, my course notes, and slides for my talks.
