Research Interests

  • Prescriptive Analytics and applications of mathematical modeling to a variety of problems, such as: product line simplification, scheduling (sports, crews, call centers, manufacturing), political districting, information display on maps, routing and transportation, location, and operations management in general.
  • Integration of optimization techniques, integer programming, constraint programming, metaheuristics and large neighborhood search.
