I am a geologist/petrologist/geochemist who investigates how our planet has evolved with time, from the deepest parts of the Earth's mantle to the continental crust and to the atmosphere. I combine field mapping and sampling with state of the art analytical tools (mass spectrometry, x-ray spectrometry, electron probe microanalysis) and simple analytical and numerical modeling. I have worked on continent formation and destruction, redox evolution of the Earth's interior, the origin of various ore deposits, the petrological structure of volcanic margins, and the origin of granites. I am now working on thegeochemical interactions between the deep Earth and oceans/atmospheres in order to better understand what controls long term climate evolution. More details on my research interests can be found on my Research and Publications pages.
