CNRS Researcher, ISTerre Grenoble, France
My background is initially in Applied Geophysics and Geotechnics (engineer degree) then I drifted to Geophysics (Tectonics and Geodesy) with a Master and a PhD at “Institut de Physique du Globe” in Paris. My PhD focused on the study of the kinematics, seismic behavior and geological history of a major fault in northern Tibet. During my post-doctoral research at the Earth and Space Sciences Department of University of California, in Los Angeles, I specialized in radar interferometry (InSAR) applied to the study of continental deformation. I joined CNRS in 2002, first at the “Laboratoire de Géologie” of “Ecole Normale Supérieure” in Paris, then at ISTerre in Grenoble since 2008.
My research mainly focuses on characterizing the behavior of active faults at different stages of their seismic cycle, combining neotectonics and geodetic (GPS, InSAR) data.
I have been trying in the past years to capture the spatial and temporal complexity of both seismic and aseismic slip on faults, with concern on InSAR methodological aspects to improve the signal to noise ratio, and with some effort to relate this complexity to fault system characteristics (earthquake history, microseismicity, geometry or “roughness” at all scales, fault zone mechanical and geological properties).
Within the FlowTrans project, I am co-advising one Early Stage Researcher (Maor Kaduri) with F. Renard and J.-P. Gratier. Our project is precisely to investigate the relationships between seismic slip, aseismic slip, and long-term properties of the fault (lithology, morphology) in the particular case of the North Anatolian fault in Turkey.
