My work is centered on using isotope tracers to investigate a variety of different processes on Earth and in the Solar System. My research interests span topics such as Cenozoic ocean chemistry and the link to climate change; hydrothermal fluid fluxes through oceanic crust; mantle geochemistry and the link between subduction and mantle plumes; the early Earth and the formation and evolution of continental crust and the mantle; and timing and effect of core segregation on Earth and other terrestrial planets. I completed my PhD in 2005 on the isotope geochemistry of thallium, and have been continuing to develop this geochemical tool since then. I am currently also involved in developing the vanadium isotope system. It is anticipated that this new tool will reveal exciting information about very diverse topics such as the oxidation state of the mantle, ocean anoxic events and evolution of nitrogen fixating bacteria.
