I am researcher (Physicienne adjointe des Observatoires) in the "Fault Mechanics" group. My research interest are the following: Aseismic processes (slow slip events) and relation with seismic observations (non-volcanic tremors) Frictionnal processes at different scales (lab earthquakes, faults) Modelling of aseismic processes using inversion of geodetic data Detection and localisation of small aseismic deformations Dynamic rupture models Source mechanics

Résumé de la fonction

Chercheur CNRS à ISTerre depuis décembre 2007, dans l’équipe geodynamo. Je m’intéresse à la physique du noyau terreste, dans lequel le fer liquide en convection génère le champ magnétique de la Terre. Pour modéliser cette Magnéto-Hydro-Dynamique (MHD), j’utilise des codes numériques (la plupart écrits par moi-même).

Physicienne des Observatoires - Full Professor
My research is dedicated to a better understanding of fault processes at various phases of their seismic cycle. I mainly use space geodesy (GPS and InSAR) to monitor the ground deformation and the space / time variations of the earth’s surface deformation. The surface deformation is generated by deeper processes affecting buried faults or magma pockets, and can therefore give us precious insigths on the stress build-up on the faults, the seismic rupture or the post-seismic relaxation. These last years, I have been mostly involved in (…)
