Research

Research interest

I am interested in faults and earthquakes dynamics, from the field to the laboratory scale. I use mainly experimental methods in order to study the different stages of the seismic cycle, from the nucleation to the propagation of the dynamic rupture.

PhD

  • Ph.D. in Geophysics, « Experimental study of the seismic rupture », Laboratoire de Géologie de l’École Normale Supérieure. Supervisors : Raùl Madariaga and Alexandre Schubnel.
