Nicolas GILLET

– my research is supported by the CNES for studies of the rapid dynamics within the Earth’s core as inferred from observations of the  Swarm  satellite mission of ESA.

– production of the COV-OBS geomagnetic field model series, from observatory, surveys and satellite observations. It now covers the period 1840-2020  COV-OBS.x2 .

– reconstructions of motions at the top of the Earth’s core from the geomagnegtic secular variation, using an ensemble approach to describe uncertainties on the flow models, within a framework involving stochastic differential equations. Several models are available on the pygeodyn portal.

– PI of the Swarm 4D Earth project (2019-2024)

– co-PI of the ANR project AVS-geomag (2011-2016)

– partner in the ANR project VSQG (2006-2009)

– here is my habilitation thesis , defended in May 2015.
