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 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.
