Research Interests:

Hydrogeophysics concerns the development of non-invasive methods to determine the geometry of water flow and the quality of water in the ground. I have been especially interested by the development of geoelectrical methods (including self-potential, electrical resistivity, and induced polarization) combining my expertise in petrophysics and the development of new algorithms.

I have been also interested by the application of these methods to a variety of problems including the contamination of aquifers, the determination of the hydraulic transmissivity of the ground, and applications of these geoelectrical properties to active volcanoes. The originality of my work lies in the understanding of macro (measurable) processes using a mecanistic approach and upscaling fundamental properties and equations known to apply to each phase or interface of the porous medium to the representative elementary volume of interest. I have devoted a large part of my research effort to the development of a quantitative approach of self-potential signals that are electrical signals, passively recorded, that affect any Earth system in a situation of non-equilibrium thermodynamics.
