My research focuses on the biogeochemical cycling of elements, and how that interacts with present and past climates. As such I am interested in chemical weathering (the Earth's primary natural CO2 removal process), soil formation chemical processes, and the effects of both on ocean chemistry. In particular, this aims to understand how the Earth's climate has responded to extreme perturbations in the past, and how we can use this information to understand future global warming. My tools of choice are dominantly isotopic, in particular developing and understanding novel methods in isotope geochemistry. Isotopic fractionation has significant advantages for understanding and quantifying elemental cycling, and hence properly getting to grips with the all-important carbon cycle.
