  • PhD Thesis offer (sept/oct 2022): Simulations Instationnaires de Suspensions de particules Solides Inertielles (pdf)

Research topics

  • Systems of macroscopic particles: granular flows and suspensions
  • Numerical simulations at the grain scale (scientific computing, numerical analysis, software SCoPI) and macroscopic modelling
  • Non-smooth contact models, stable algorithms (non-smooth convex analysis, constrained optimization)
  • Direct numerical simulations of rigid particles embedded in a Stokes fluid (penalty methods, boundary element methods)
  • Numerical treatment of the hydrodynamic singularity due to close particules in suspensions (lubrication)
  • Micro-swimmers: control and optimal control for swimming problems
