About me
My Story
After studying Earth Sciences in Paris and Montpellier, I did a PhD in Lille (1999-2002) on fluid migration in the Congo Basin. After a 5-year post-doctorate in Southampton, I became a lecturer at the University of Montpellier in 2008. I am now a specialist in fluid migrations from their source to the surface (ground or seabed).
