My research focuses mostly on optimization. It includes nonsmooth optimization, stochastic optimization, power systems optimization and stochastic processes. I have been combining theoretical research in optimization with practical issues of relevance for industrial problems. Some of my industrial applications are:

  • Petrobras: Petroleum management   (on-going project)
  • Petrobras: Natural gas management
  • LabPlan/UFSC: Optimization techniques for thermal unit commitment problem
  • Électricité de France: Power systems management, the French case
  • Eletrobras-Cepel: Power systems management, the Brazilian case.


I am a member of the scientific committee of the International Seminar on Optimization and Related Areas - ISORA, to be held on October 9-13, 2017, in Lima, Peru at the Instituto de Matemática y Ciencias Afines - IMCA.

I have been invited to be a semi-plenary speaker at the Congresso Nacional de Matemática Aplicada e Computacional - CNMAC 2017, wich will take place in São José do Campos, Brazil,  on September 19-22.
