I am Professor in geodynamic at University Grenoble Alpes.
I am currently working on transform faults in the continental lithosphere bear witness to the Earth’s dynamics. They are the result of a succession of events that occur at of scale hundred millions of years to the second. My studies aim to understand how these major faults have been structures, by reconstructing these events using a variety of approaches. Initially, I focused on long-term deformation of the continental lithosphere (ten million years), with an emphasis on the fossil subduction zones (Himalayas, Papua New Guinea, Cyclades) and the limits of the Tibetan plateau (Himalayas, Longmen Shan). For the past 10 years, I have been developing and combining tools for the study of the seismic cycle of slow faults (at scale of thousands of years). To do this, I bring together a group of researchers from very different disciplines (sedimentology, geophysics, active tectonics, archaeology, psha). I chose the ancient city of Nicaea, close to the North Anatolian fault. In the lake, a buried world emerged, raising questions about the history of Christian civilization and the evolution of a city subject to seismic hazards, as echoed in the film " Iznik The Secrets of the Buried Basilica ".
