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, INFORMS Journal on Optimization, Transportation Science, all of which are indexed in the Thomson Reuters Journal Citation Reports.
