Brief Biography

After studying Mathematics at the University of Rennes 1, I obtained a master (1988) and a  Ph.D. in Computer Science (1991) in the IRISA/INRIA laboratory, in the ADP team, under the supervision of Claude Jard and Michel Raynal. 
From 1991 to 1992, I was a research engineer in the Alcatel Alsthom research lab in Marcoussis near Paris.
In 1993, obtained a position as INRIA research scientist (Chargé de recherche) in the Pampa team in Rennes where I did my research work for 8 years.
From 2001 to 2012, I was the scientific leader of the VerTeCS team.
I obtained my Habilitation from University of Rennes 1 in March 2004 (text , video , slides).
From 2011 to 2015, I was the Vice-Chairman of the projects committee of Inria Rennes - Bretagne Atlantique and member of the Inria Evaluation Committee.
From 2013 to 2023, I was a member of the SUMO Irisa/Inria team.
Since 2024, I am a member of the DEVINE Irisa/Inria team headed by Nathalie Bertrand.






Research Topics

My research topics concern the formal verification and  validation of large and reactive systems:

• Verification of large distributed systems.
• Verification, testing, learning of timed systems.
• Model-based testing: models and theory for conformance testing of reactive systems, automated test case synthesis with symbolic techniques for diverse models, with data, time, recursion.
• Diagnosis of Discrete Event Systems: models, theories, algorithms for the construction of diagnosers, verification of diagnosability.
• Monitoring and enforcement of timed properties.
• Security: security testing, diagnosis for intrusion detection.
• Verification of asynchronous communicating systems with approximate analysis.




Publications

• TGV is a test generation tool for models of labelled transition systems (LTS). The generation of test cases is guided by a test purpose (an automaton) and is based on "on-the-fly" co-reachability analysis of enumerated transition systems.
  
• STG is a test generation tool for models of transition systems extended with data variables and parameters (STS). Test generation from a system model and a test purpose is based on syntactic transformations of STS using approximate analysis (provided by the NBAC tool).
