Current Research Activities

• Formal conformance testing
• Satisfiability checking
• Analyzing safety of machine learning models
• Formalisation and verification of normative requirements

Educational Background

I did my PhD in the CONVECS team at Inria, under the supervision of Professor Radu Mateescu, Professor Ioannis Parissis, and Professor Wendelin Serwe. I defended in December 2019 my PhD thesis, entitled "On Model-based Testing of GALS Systems". I received an MSc degree in computer science in 2016 from the University of Grenoble and my bachelor degree in computer science in 2014 from the University of Strasbourg.

Formal models

• Autonomous Vehicles in LNT for Simulation and Testing

  I have formalised two behavioral models of an autonomous vehicle (AV) and its interaction with the environment, in collaboration with Lucie Muller, Radu Mateescu, and Wendelin Serwe. The first model is used to validate the overall AV, and the second model is used to validate the perception component via autonomous driving scenarios generation and testing. Both models are formalised in LNT, and we used the CADP toolbox to check them.

• Message Authenticator Algorithms:

  I reconsidered the formalisation of a message authentication algorithm (MAA), in collaboration with Hubert Garavel. We formalized the MAA in LNT, LOTOS and term rewrite system (in the REC language), and used the CADP toolbox to check our models. I also formalized the MAA in LUSTRE and SCADE, and used the LURETTE and SCADE tools to test these models.

• The Transport Layer Security (TLS) Protocol Version 1.3:

  As part of a Hubert Curien partnership (PHC Amadeus program of Campus France, RIDINGS), with the INRIA team CONVECS, we were collaborating with the Graz Institute of Software Technology in Austria. With my colleagues from IST Graz, I worked on the formalization in LNT, and validation of the first formal model of the Draft TLS 1.3 handshake protocol for securing exchanges on the Internet.
