I am currently a graduate student in the Earth and Space Sciences Department at University of Washington, working with Kenneth Creager.

From 2006 to 2015, I was a research engineer at BRGM (French Geological Survey), France’s reference public institution for earth science applications in the management of surface and subsurface resources and risks.
During the academic year 2015-2016, I was working with Jeroen Tromp and Frederik Simons in the Geosciences Department at Princeton University.

I am currently interested in detecting the presence of water in the subducting Juan de Fuca plate, in order to better understand the seismogenesis and the consequent seismic hazard. I use recordings of Low Frequency Earthquakes (LFEs) by seismic arrays in the Olympic peninsula during several events of Episodic Tremor and Slip (ETS), in order to invert for the velocity contrasts associated with the plate interface and the subducted oceanic crust and Moho. Due to the convenient location of the LFEs close to the upper boundary of the subducted plate, the seismic waves should illuminate well the area around the subducted plate, and highlight the presence of a low velocity zone, characteristic of the presence of water.

My other research interests are:
  • Full-waveform inversion of velocity structure using wavelet-multiscale and adjoint-based methods.
  • Velocity structure inversion using horizontal-to-vertical (H/V) spectral ratios of earthquake motions.
  • Seismic wave propagation.
I graduated from Ecole Centrale Paris, majoring in applied mathematics.
