Research

The main focus of my research is on the development of mathematical programming tools for the solution of hard combinatorial optimization problems arising in logistics, transportation and data science. I search for either highly specialized tools that exploit the very particular structure of the underlying optimization problem, or for general tools applicable to a broad class of problems. In the last years, I have been working on tools aimed at enhancing column generation-based algorithms for several different applications. My works have been published in journals like INFORMS Journal on Computing, Discrete Optimization, NetworksComputers & Operations Research and European Journal of Operational Research, all of which are indexed in the Thomson Reuters Journal Citation Reports.

My research is constantly being developed in collaboration with students and colleagues in Montréal and abroad. I am a full member of two of the most recognized research centers in operations research in the globe, notably the CIRRELT and the GERAD. While my funding is limited, I am in constant search of bright and motivated students willing to pursue graduate studies under my supervision. These students need to have a strong background in mathematical programming, discrete optimization, and/or programming.
