Research activities

My work is dedicated to the development of formal methods for validation and verification of software systems. More precisely, I am interested in software testing approaches based on verification techniques, like proof or model-checking.

My work follows three main directions:
  • Testing functional aspects of systems, where the expected behaviour of the system is specified in a first-order formalism.
  • Testing reactive aspects of systems, where the formalisms used for specification may be either modal logics or transition systems.
  • Testing concurrent aspects of distributed systems, whose behaviour is specified with Message Sequence Charts or Petri nets for instance.
