His research interests focuses on the composition and evolution of the continental crust, crust-mantle interactions and the origin and evolution of the solar system. To address these questions, he studies both terrestrial and extra-terrestrial materials through analyses of non-traditional stable isotopes (lithium, magnesium, iron, copper, zinc etc.). His research techniques involve both purification of targeted elements through column chromatography in a clean sample preparation laboratory and high-precision isotopic analyses using High Resolution Multi-Collector Inductively Coupled Plasma Mass Spectrometry (HR-MC-ICPMS).
