    • Research topic : Higher Dimensional Automata for games and verification

    My research focuses on formal verification for automata and higher dimensional automata. My main models are based on automata and its variants (Timed, Higher Dimensional Automata) in order to have more expressive models to fit reality. My aim is to work on games and robustness for HDA and its variants. I am also interested in logic and geometric aspects of HDA.

    A second interest of mine is geometry and groups. I study it both for verification purpose (polyhedra tiling for some optimisation function in verification, algebraic structure of models) or for more mathematical sujects (e.g random groups).

    Keywords :

  • Automata, Higher Dimensional Automata, Model-Checking, Temporal Logic (LTL, HyperLTL...), Games on graphs, Robustness
  • Polyhedra, Symbolic optimisation
  • Random Groups, Geometry

    • You can find below a sum up of my four main research topic.

    Concurrency : Higher Dimension Automata

    My goal is to provide verification for models of concurrency, as higher dimensional (timed) automata (HDA/HDTA). This model is based on automata and events can happen in parallel (true concurrency).
    My research focus are on :

  • Development of logic for Pomsets
  • Comparison of concurrent models
  • Verification and robustness

    • Collaborators : Amazigh Amrane, Hugo Bazille, Aloÿs Dufour, Enzo Erlich, Uli Fahrenberg, Marie Fortin, Léo Henry, Jérémy Ledent, Benjamin Monmege, Philipp Schlehuber-Caissier, Krzysztof Ziemiański

    Monitoring


    I aim to provide online monitoring algorithm based on automata techniques.
    My goals are to :

  • Compare traces (Hyperproperties, HyperLTL)
  • Provide a user-friendly language specification
  • Applied monitoring to use-cases (ex: malwares)

    • Collaborator : Étienne André

    Random groups

    Groups can be randomly generated with letters (generators) and cancelling subwords (relation). My goal is to study the asymptotical behaviours of such groups, depending on the length of the relations. In particular :

  • Are these groups free ? Hyperbolic ?
  • Can we splits them ?

    • Collaborator : John Mackay
