Scientific research

My scientific research at Lagrange Laboratory focuses on studying the petrology/geochemistry of primitive meteorites and of their pristine constituents (refractory inclusions, chondrules, metal) to shed light on the early evolution of our Solar System. I am also designing dedicated high temperature experiments for reconstructing the formation conditions of primitive objects and their astrophysical setting of formation. Finally, I am performing thermal shock or hypervelocity impact experiments for understanding the evolution of asteroidal surfaces.
With expertise at the Materials/Geosciences/Astrophysics interface, I am Co-I OSIRIS-REx, Hayabusa2, MMX and Hera space missions. For OSIRIS-Rex, I am in charge of high-resolution cathodoluminescence analyses of returned samples in Mineralogy & Petrology Working Group.

Scientific supervision

I have supervised:
- 16 PhD thesis : Lydie Le Forestier* (1996); Jerôme Sterpenich* (1998); Franck Humbert (1998); Peggy Georges* (2000); Nathalie Valle* (2000); Catherine Maieron (2001); Laurent Tissandier* (2002); Benoit Marcq (2003); Alice Toppani* (2004); Christophe Cloquet (2005); Sebastien Bouquain (2007); Aurélie Verney-Carron* (2008); Romain Mathieu* (2009); Johan Villeneuve* (2010); Maia Kuga (2014); Soulie Camille (2014).
- 7 post-docs : M. Toplis*(1993-1994, now Director of Observatoire Midi-Pyrénées, Toulouse); F. Faure*(2002- 2003) ; A. Pack*(2003-2005); A. Morlock*(2007-2009); A. Kropf(2009-2011); R. Noguchi(2009); M. Niezgoda (2011-2012); L Piani* (2012-2013). *now with permanent position in academic research.
- I participated in 74 PhD thesis juries and 17 HDR ; 16 during the past 5 years.
