Advisor(s): Tom Zega


Pierre is a cosmochemist working with Prof. Tom Zega and the Earths in Other Solar Systems (EOS) team ( on the characterization and coordinated in-situ study of primitive organic matter in meteorites and interplanetary dust particles.

He grew up in Brussels (Belgium) and graduated with B.A. and M.S. degrees in Geology and Geochemistry from the Free University of Brussels. He then moved to St. Louis (Missouri) and obtained a M.A. degree and a Ph.D. in Earth and Planetary Sciences from Washington University in St. Louis. His background is in geochemistry and cosmochemistry, from terrestrial samples (e.g., Pb and Zn isotopes in Archean komatiitic lava flows) to primitive extraterrestrial samples (e.g., meteorites and micrometeorites), using multi-collector inductively coupled plasma mass spectrometry and a variety of in situ ion- and electron-microscopy techniques (e.g., secondary ion mass spectrometry, Auger and Raman spectroscopy, focused-ion-beam scanning-electron microscopy and transmission electron microscopy). His research interests focus on the building blocks and early history of the Solar System history, and the origin of life. In particular, his doctoral research work focused on the identification and coordinated micro-analytical study of circumstellar (presolar) grains in primitive meteorites and fine-grained micrometeorites.
