Mathilde RADIGUET

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

Biography

I studied Geophysics at Ecole Normale Supérieure, Paris, France for my bachelor and Master. During my master thesis I worked on the relations between earthquake ground motions and fault characteristics at ISTerre (Grenoble, France), under the supervision of F. Cotton, I. Manighetti and M. Campillo.
I obtained my PhD in Geophysics from the University of Grenoble, France, in the Institut des Sciences de la Terre (ISTerre). There, I studied a specific mode of fault rupture, the slow slip (…)
