An important part of my research consists of developing synthetic aperture radar (InSAR) methodologies to measure slow surface displacements (few mm/yr) associated with various processes (active tectonics, surface processes, permafrost, etc...). Another research interest is to reconcile long-term (geological or tectonic) and short-term (geodetic) tectonic models. I am particularly interested in the link between fault behavior and fault geometry, or how to create long-term topography with repeated seismic cycles.
