He holds a Ph.D. in Planetary Sciences and was formerly a post-doc at Laboratoire AIM(CEA-Saclay, France).
His research topic is the exploration of planetary surfaces with remote sensing. He studies the seasonal processes on Mars with OMEGA and CRISM hyperspectral images, focussing on the role of seasonal water ice deposits in the present martian water cycle.

A montage of 18 of the 20 asteroids and comets that have been photographed up close as of December 2018, when New Horizons flew past Arrokoth. This version is in color but does not show the bodies at their correct relative albedo or brightness. Not included are Vesta or Ceres, both of which are many times larger than Lutetia.
While atop Vera Rubin Ridge, Curiosity stopped at a site called Bressay that had a jumbled collection of various Gale rocks. The left image is from Mastcam, the right from ChemCam, colorized with the Mastcam data.
