I would rather have today's algorithms on yesterday's computers than vice versa. - Phillipe Toint
The purpose of computing is insight, not numbers. - Richard Hamming

Research interests

  • graph homomorphisms
  • structural graph theory
  • algorithms in graph classes
  • algorithms for NP-hard problems
  • geometric representations of graphs
