chemical evolution of the Earth
measurements of novel isotopic systems
Areas of expertise
My research focuses on the chemical evolution of the Earth. As such I am interested in planetary formation and differentiation, sampling of the hidden Earth via melts, interaction of the deep and surface reservoirs and how this has influenced the terrestrial 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.
