Curriculum Vitae

Scientific interests

My research is focused on numerical analysis and scientific computing, with emphasis on finite element methods and boundary/interface conditions such as it occurs in fluid-structure interaction and contact/friction. It encompasses both theoretical aspects (proofs of stability and optimal convergence) and applied aspects (multi-disciplinary projects and industrial / biomedical applications).

Main applications fields are solid/fluid mechanics and biomechanics. For instance :

  • Computational contact mechanics applied to tyre simulation. It involves an industrial partnership with Michelin France, materialized by the PhD of Rabii Mlika, with CIFRE funding, and co-supervised with Y. Renard (INSA Lyon) and J.F. Deldon (Centre de Technologie Michelin).
  • A posteriori error estimation for soft-tissue biomechanics (within the framework of the CNRS multi-disciplinary project Defi Infinity "MEFASIM" granted for 2017). It involves as well an industrial partnership with TexiSense and a multi-disciplinary collaboration between mathematics, computational mechanics, biomechanics and computer science.
