Dominique JAULT

I am working to improve the knowledge of Earth’s core dynamics. To this end, I am conducting researches about the Earth’s magnetic field and its temporal variations. My work benefits from analyses of magnetic data that are presently collected from the 3 low orbiting satellites of the ESA’s Swarm constellation. It presently consists in:

inference of mantle electrical conductivity from the investigation of Earth’s core dynamics
detection of wave-like motions in the liquid core and investigation of their propagation
development of a reduced "quasi-geostrophic" model of the fast dynamics within the Earth’s core

These works are supported by CNES, ESA (Swarm+4D Deep Earth: core project) and ERC (https://graceful.oma.be/).

I supervise the thesis of Thea Lepage (co-supervisor Nicolas Gillet) about the electrical conductivity of the lowermost mantle.

Biographical sketch

Dominique Jault has been a CNRS research associate, and then senior researcher since 1991. He worked at IPGP (Institut de Physique du Globe, Paris) up to 1997, then moved, together with H.-C. Nataf and Ph. Cardin, to LGIT (Laboratoire de Géophysique Interne et Tectonophysique, now merged into ISTerre) at the University Joseph-Fourier of Grenoble (now merged into University Grenoble Alpes). He was head of LGIT from 06/2002 to 12/2006. He has spent one year at the Department of Mathematics of (…)
