Research interests and active projects

Stable isotope study by ion microprobe of melt inclusions in mantle rocks and of inclusions in mantle minerals (source compositions, interactions with the crust)

B isotope fractionation in the surface cycle, in particular during weathering processes in soils

Environmental changes on the Earth during the archean from the isotopic study of archean metasediments

Isotopic studies of SNC meteorites related to their petrogenesis

Cosmochemistry of Li-Be-B elements with a special emphasis on their presolar and solar nucleosynthesis

Irradiation processes in the early solar system (Li, B, C and N isotopic composition of the Solar wind, isotopic studies of refractory inclusions in chondrites and of iron meteorites)
