Research Experience:


  * December 2001 - present
    INRIA (Institut National de la Recherche en Informatique et en Automatique),
    Sophia-Antipolis, France.
    Post - Doctoral Research, Computational Mechanics in Aerospace Engineering.

    Keywords: Computational Fluid Dynamics, Optimal Shape Design, Aeroelasticity,
    Supersonic Flows.

    Granted by the French Ministry of Research.
    Development of shape optimization techniques for supersonic flows coupled with
    structures in aerospace applied research. The goal is to optimize
    the wing shape of a supersonic aircraft in order to
    reduce the so-called sonic boom produced by the shock wave ahead of the plane,
    which has a dramatic acoustic environmental impact.
    The optimization scheme takes into account the aircraft's structural deformation.
    The geometries to optimize are provided
    by Dassault Aviation, corresponding to a new supersonic civil jet.


  * March 2000 - October 2001
    Pole Scientifique Dassault Aviation / Universite Pierre et Marie Curie, Paris.
    Post - Doctoral Research, Computational Mechanics in Aerospace Engineering.
   
    Keywords: Computational Fluid Dynamics, Turbulent Flows, Multigrid, Incompressible Flows,
    Compressible Flows
   
    Granted by the European Comission.
    Development of speed-up convergence
    algorithms by the so called multigrid method, in turbulent
    compressible and incompressible flows, 2D and 3D, solved
    using implicit schemes. Study of turbulence physical models
    (RANS models) and their computational implementation 
    by the Finite Elements Method.
    This work focused mainly on the robustness of the
    scheme, to render it as reliable as possible to aeronautic engineers.


  * 1993 - 2000
    CIMNE (International Center for Numerical Methods in Engineering), Barcelona.
    Doctoral and Post - Doctoral Research, Computational Mechanics in Aerospace Engineering.
   
    Keywords: Computational Fluid Dynamics, Compressible Flows, Turbulent Flows,
    Incompressible Flows, Multigrid

    Partially granted by NASA Ames Research Center.
    Development of a general algorithm for the numerical solution
    of the Navier - Stokes equations, using fractional step techniques.
    Compressible and incompressible flow, laminar and turbulent regimes (RANS models),
    solved using explicit and semi-implicit schemes, by the Finite Elements Method. Study of speed-up
    convergence techniques, in particular, multigrid.
