Research interests include:

The geology, physics and chemistry of the formation of the Earth's lithosphere. Early evolution of oceanic rift systems. Partial melting in the mantle and the petrogenesis of mid-ocean ridge basaltic magmas. The isotopic evolution of Nd, Sr, Pb and Os in the upper mantle. Mantle noble metal geochemistry, including Re-Os and Pt-Os isotope geochemistry. Low-temperature mantle/seawater chemical exchange at ridges. The tectonics of fracture zones, and the petrology and structure of oceanic lower crust and upper mantle exposure.
