Research Interests

My research focuses on chemical and isotopic heterogeneity in the mantle. In particular, I am interested in determining the magnitude and spatial distribution of such heterogeneities and determining the implications of these anomalous compositions in various tectonic settings. I use a variety of isotope systems to investigate these problems and collaborate with a number of research groups in Europe and the US. My current research interests are relatively diverse but have a common peridotite theme:

The Pb paradox and Os isotopic gap: the role of mantle sulphides as refractory domains. With Steve Shirey (Carnegie Institution, Washington) Jessica Warren (Stanford University), Al Brandon (University of Houston), Marjorie Wilson (University of Leeds), Janne Koorneeff (Vrije University)

The effects of melt depletion, metasomatism, and supergene weathering on S-Se-Te and PGE in pyroxenite xenoliths from Kilbourne Hole, NM. With Stephan König (University of Bonn), Ambre Luguet (University of Bonn)

The nature and extent of stable isotope (Zn, Cu, Mo, V) fractionation in mantle peridotites. With Paul Savage (University of Durham), Alex Halliday (University of Oxford), Yu-Hsuan Liang (University of Oxford), Julie Prytulak (Imperial College London)

Quantifying the hydrated inputs to subduction zones - a boron isotope study of fast and slow spreading mid ocean ridges. With Andrew McCaig (University of Leeds), Ivan Savov (University of Leeds)
