Jean-Louis Grimaud - Research Assistant, MINES ParisTech

My research is about some aspects of the large-scale routing of sediments from continental domains to sedimentary basins. The general question is what remains of surface dynamics history in landscapes and stratigraphic records. I study "flat" landscapes such as cratons and alluvial plains (West Africa, the Bengal basin, or the Ain and Seine Rivers) and have developed skills in experimental modeling of geomorphic systems.
