In recent years, my academic career has been more focused on administration, but I am still very interested in several research areas, including

  • Scientific computing
  • Parallel algorithms
  • Numerical analysis
  • Nonlinear differential equations
  • IT system administration
  • Computer architecture
  • Computational humor
  • Applications of humor and improvisation
