Regis Duvigneau
Researcher in Scientific Computing

I am senior researcher (DR2) in Acumes, joined project-team from Inria Centre at Université Côte d'Azur and Jean-Alexandre Dieudonné mathematics laboratory.
My research is focused on numerical methods for analysis and optimization of systems governed by PDEs, with particular emphasis to fluid mechanics.

Academic background
Some recent achievements
Isogeometric analysis

I develop NURBS-based Discontinuous Galerkin schemes, allowing exact-geometry simulations for compressible Euler and Navier-Stokes equations, including local refinement, shock capturing, arbitrary Lagrangian-Eulerian formulation and sliding grid.

Scientific machine learning

I investigate machine learning algorithms, in particular Physics-Informed Neural Networks, for parametric surrogate modeling, multi-physics coupling and hidden physics inference.

Sensitivity analysis

I study methods for sensitivity analysis, focusing on hyperbolic systems including discontinuities, and time-dependent high-order sensitivities.

Software

I develop the IGLOO software suite for isogeometric simulations, that targets a seamless CAD-analysis integration. This software is distributed under the GNU General Public License v3 (code repository).
