Olivier Le Maitre

Visiting Academic-Professor​

Research Interests

  • Development of numerical methods for the analysis of models parametric uncertainties; in particular stochastic spectral methods and multi-resolution schemes with associated solvers and algorithms for Galerkin and non-intrusive methods.
  • Application of these methods to complex flow models, system of conservation equations, elliptic problems and reactive systems.
