Jean-Louis Grimaud

Biography

Jean-Louis Grimaud is a researcher specializing in geomorphology and the dynamics of sedimentary systems. His work focuses primarily on the evolution of river systems, landscape incision, and the modeling of erosion and sedimentation processes at various spatial and temporal scales. His research integrates approaches that combine digital elevation model (DEM) analysis, field mapping, and geostatistical modeling to study the interactions between tectonics, climate, and the dynamics of continental surfaces. Grimaud has notably contributed to our understanding of river capture mechanisms, long-term incision rates, and the redistribution of regolith in various geological contexts, such as the ultrabasic massifs of New Caledonia and European sedimentary basins. His recent work also explores the processes of sedimentary record preservation, the architecture of alluvial deposits, and the dynamics of submarine turbidite systems, with applications in georesources and paleoenvironment.

Teaching

Geoscience and the Anthropocene (GA)

Course Director

The “Geosciences and the Anthropocene” GA course takes place at several sites impacted by human activity, specifically chosen to deepen students’ understanding of the challenges related to climate change and the energy transition. This course is organized as a one-week intensive off-campus session. For logistical reasons related to the large number of students, the class is divided into six groups working independently under the guidance of a multidisciplinary teaching team. The six groups will be based in the following areas: Paris and Morvan (Île-de-France) Digne-les-Bains and surrounding area (Alpes-de-Haute-Provence) Laragne and surrounding area (Hautes-Alpes) Romanche and Drac Valleys (Isère and Hautes-Alpes) Western Pyrenees (French and Spanish) Roya Valley (Alpes-Maritimes) For each group, the teaching team consists of 2 to 3 faculty members, each of whom will supervise a group of 8 students. Within these small groups, instruction will alternate between observation sessions of natural objects, independent work sessions in which students are invited to observe and analyze the geological terrain relevant to the instruction they have received, tutorials, and visits to key sites or engineering structures. Over the course of the week, each team will present the results of their workshops to all the students in their group.
