Research Interests

Understanding the formation of the solar system through meteorite study (mainly carbonaceous chondrites and ureilites)

Asteroidal parent body aqueous alteration and thermal metamorphism history

Origin and evolution of organic matter; silicate serpentinization in chondrites

Nanoscale analyses of meteoritic materials using combined analytical techniques (Transmission Electron Microscopy, Raman Spectroscopy, Scanning Transmission X-ray Microscopy and NanoSIMS)


Present situation

Post-doctoral fellowship funded by the DFG - SPP1385 « the 10 first million years of the solar system, a planetary material approach » (Le Guillou C. and T. Mueller)

Project title : Hydration of amorphous silicates in the early solar system: An experimental kinetic study.
In coll. with T. Mueller, R. Dohmen and S. Chakraborty (RUB); C. Vollmer and A. Putnis (Muenster) and A. Brearley (University of New Mexico, USA).
