Throughout my career, I have explored the Earth’s magnetic field from ground observatories to satellite missions, modelled the core field and its time variations, and used magnetic observations to investigate the deep Earth, including the conductivity of the lower mantle and fluid dynamics at the core–mantle boundary. I have also extended this perspective to planetary magnetism, studying the magnetic environments of planets such as Mars, Mercury, and Venus.

Today, I serve as Head of the Science Coordination Department at CNES, where I help guide scientific strategy and foster collaborations across the geosciences and space research communities.

I have always enjoyed sharing knowledge – mentoring students, supporting young researchers, and contributing to the scientific community through collaborative projects and service roles. Helping others grow in geophysics and planetary science remains one of the most rewarding parts of my career
