Présentation

My research interest are around inverse problem for measurements that come from a physical model (a PDE). I worked on Sampling method that provides geometrical information of the unknown, on spectral signature to extract quantitative information in a non iterative way and on more classical optimisation based approach. I enjoy real applications comming from non destructive testing.
