About Me

I am a Senior researcher at Inria and Ecole Polytechnique (member of the Laboratory of Solid Mechanics, and adjunct professor in the department of Applied Mathematics), Inria team-leader of MΞDISIM (Mathematical and Mechanical Modeling with Data Interaction for Simulation in Medicine)

My main research concerns inverse problems, in particular identification problems or data assimilation problems in general for partial differential equation models, in which I seeking from designing and analyzing original methods. I am also very concerned by the efficiency of the proposed methods so that they can be used in real application context. I have particularly worked on applying these new methods to solve model-based estimation problems on the cardiovascular system. More precisely in the field of data assimilation approaches, my main investigations concern observer-based methods from an optimal control point of view or from a stabilization point of view.

As my ambition is also to go up to the application, an important part of my researched is also devoted to modeling and the numerical aspects (computational methods and numerical analysis) of bomechanical systems such as the ones encountered in cardiac mecahnics (non-linear mechanics, active soft tissue, fluid-structure interaction, poroelasticity, reaction-diffusion). My direction of research in the modeling aspects is to propose well-balanced formulation since they are a prerequesitve for defining adequate stable observer when reconsidering them in the estimation process.
