I am an Assistant Professor at University Joseph Fourier (UJF, France) since 2001 after completing a 2-years postdoctoral Scholarship at Pau University (France). I obtained a PhD in Geophysics in 1999 and the “Habilitation à Diriger des Recherches” diploma of UJF in 2010. My research focuses on multi-method geophysical characterization of various natural hazards, such as gravitational instabilities (landslides and rockfall), active faults, seismic site effects and glacial hazards. He is also interested in the multiphasic character of geological formations, by considering fluid’s effect in wave propagation imaging (seismic, electromagnetic, seismo-electromagnetic). This quantitative imaging problem is of interest in environmental, hydrological, natural resources (oil, CO2) or geotechnical engineering problems. All of the research proposed was based on real data (active or passive), implying a large number of field and laboratory campaigns conducted in France and outsides (Italy, Antarctic, New-Zealand, Laos, Ecuador ...). For quantitative interpretation of these data, methodological advances were sometimes proposed by combining theoretical and/or numerical developments with geophysical inversion. It includes the potential of seismo-electromagnetic wave conversions in poroelastic materials, thin layer characterization for stability assessment using Ground Penetrating Radar (GPR) and also Full Waveform Inversion approach on seismic and GPR data for georesources (Seiscope Consortium) and environmental purposes. In addition, a large range of geophysical or geotechnical methods have been used depending on the context for joint interpretation and monitoring (Seismology, Geodesy, boreholes). A large part of this work was published in more than 40 international papers.
