Jérôme Dyment 

Université Paris Cité, Institut de physique du globe de Paris, CNRS




Jerome Dyment is CNRS Senior scientist at Institut de Physique du Globe de Paris, France. His research interest focuses on marine magnetic anomalies, to 1) date and reconstruct the structure and evolution of ocean basins, 2) depict the structure and magnetic properties of the oceanic lithosphere and understand active processes at mid-ocean ridges, and 3) refine the history of the geomagnetic field to constrain its mechanisms. Holding an Engineer Degree and a PhD IN Geophysics (Strasbourg, resp. 1987 and 1991), he is the author of more than 90 scientific publications, supervised 10 PhD theses, participated 20 scientific cruises (9 as chief scientist), and is or was PI of French and bilateral scientific projects with, for the most recent ones, India, Mauritius, Japan, Korea, and Indonesia. Among various community tasks, he has been the advisor of CNRS Director for marine geosciences (2006-2011), the president of the French committee associated to the International Union of Geodesy and Geophysics (2010-2014), the head of the Marine Geoscience Team of Institut de Physique du Globe de Paris (2013-2016), and Steering Committee member (2001-2010) and the chair (2016-2020) of InterRidge.  He is also leading the Task Force appointed by the International Association of Geomagnetism and Aeronomy to build the World Digital Magnetic Anomaly Map.
