Research interests

Generally speaking, I act as an historian of the first million years of the solar system, as the young Sun was still surrounded by a protoplanetary disk, by taking advantage of the meteoritical record (and especially that of chondrites). This involves observations, chemical and isotopic analyses of samples as well as astrophysical modelling.

A few specific research topics

• Chondrule formation: trace element geochemistry and constraints on thermal history and the nature of precursors, constraint of size, effect of collisions in the shock wave scenario.

• Transport of chondrite components: problem of the retention of refractory inclusions, of the matrix-chondrule complementarity, interpretation of the bulk chondrite fractionations (especially between carbonaceous and non-carbonaceous chondrites)

• Dust concentration mechanisms: dust/magnetohydrodynamical turbulence interaction, linear streaming instability.
