The INRIA project-team OPALE is located in both the Sophia Antipolis – Méditerranée Research Center near Nice and in the Grenoble Rhône-Alpes Research Center.


  • analyze mathematically single or multi-disciplinary coupled systems of partial differential equations arising from physics or engineering in view of their optimization or control (geometrical optimization);
  • construct and experiment efficient numerical approximation methods (coupling algorithms, model reduction) and optimization algorithms (gradient-based and/or evolutionary algorithms, game theory);
  • develop software platforms for the distributed parallel computation of the related discrete systems;
  • use mathematical tools to develop models for vehicular and pedestrian traffic;
  • use mathematical tools of optimization and control to develop models in biology and medicine.
