Research interests

My research consists of the study of the formation of the solar system from its building blocks, the chondrites, to the evolution of terrestrial planets such as Earth and Mars in a global geodynamic context as revealed by isotope geochemistry. I am also interested in the formation of chemically distinct reservoirs in planets and mixing between these reservoirs, mantle convection, mantle plumes, the role of the source mineralogy and of plate teconics and early planetary differentiation. To examine these issues, I am using several radiogenic isotope systems (Rb-Sr, Sm-Nd, U-Th-Pb, Lu-Hf, Re-Os), including short-lived system 142Nd. I am also interested in the habitability of planets, i.e. when a planet could have sustained life, even if life did not appear. I am currently participating to the Mars2020 mission as one of the five Return Sample Scientists selected by ESA.
