Current position

Research engineer at ISAE-SUPAERO in the Applied Mathematics group of DISC since September 2016.

Past position

Senior scientist in the Parallel Algorithms Project at CERFACS.


November 2017 : For second year students : two PIR projects on scientific computing and numerical methods have been proposed. Please contact me if you are interested !

October 2017 : A paper on parallel in time methods for CFD applications with Julien Bodart, Thibaut Lunet and Serge Gratton has been accepted. It is mainly related to the Parareal algorithm with spatial coarsening.

 Research interests

My primary research interests are scientific computing, in particular, the design and analysis of numerical algorithms for the solution of partial differential equations and related high-dimensional linear algebra problems, and parallel algorithms.

  • Fast iterative solvers for large systems of linear and nonlinear equations
  • Krylov subspace methods and preconditioning
  • Multigrid and domain decomposition methods
  • Parallel computing including parallel in time methods

My current research is on high performance and large scale computations with a focus on the analysis of data from scientific simulations.
