Research Interests

• Applications of Operations Research techniques to a variety of practical problems, such as: product line simplification, scheduling (sports, crews, machines), computational geometry, transportation, location, and operations management in general.

• Integration of optimization techniques.
• Integer Programming and Constraint Programming.
• Metaheuristics and large neighborhood search.
