My research thematics is the characterization of the seismic source by inversion of seismological and geodetic data. I use source point and extended source approaches for estimate 1D seismic velocity models, focal mechanisms, and coseismic slip distribution. I also worked on the non-uniqueness of the best solution given by global inversion methods by the developpement of a procedure to build an average rupture model from the combined results of several joint inversions.
