Expertise
I am an isotope geochemist who studies planetary formation and evolution. Specific interests range from modern geological processes to meteorite cosmochemistry, using an approach that focusses on high precision isotope analyses.

Research interests
My research focuses on the chemical evolution of the Earth and other rocky bodies. I am interested in the history of the solar nebula, planetary formation and differentiation, sampling of the hidden Earth via melts, interaction of the deep and surface terrestrial reservoirs and how this has influenced the surface environment.
My tools of choice are dominantly isotopic, in tandem with elemental abundance measurements and judicious application of petrology and fieldwork. I have developed measurements of novel isotopic systems and am enthused by the new vistas of isotopic determination offered by plasma mass-spectrometry and their combination with collision cells.
