Biography
Combinatorial optimization: I specialize in high-performance solvers based on branch-and-cut-and-price, an advanced technique of mixed integer linear programming that includes Dantzig-Wolfe reformulation, column generation, cutting planes, polyhedral analysis and Benders decomposition.
Routing, scheduling and path planning: I develop hybrid algorithms that exploit the strengths of integer programming at routing, constraint programming at scheduling and heuristic search at path finding to solve joint problems faster than any technology alone. This work is applied to automated decision-making problems in the transportation, logistics and warehousing sectors.
