My research focuses mostly on optimization. It includes nonsmooth optimization, stochastic programming, mixed-integer optimization,
energy and power systems management. I have been combining theoretical research in optimization with practical issues of relevance for the industry of energy. Some of my previous industrial applications are:
  • Petrobras: Petroleum management  
  • Petrobras: Natural gas management
  • LabPlan/UFSC: Optimization techniques for hidrothermal unit-commitment problems
  • Électricité de France: Power systems management, the French case
  • Eletrobras-Cepel: Power systems management, the Brazilian case.
