Personal profile

Research interests

My research centres around developing techniques to measure isotope systems to high-precision and accuracy by thermal and plasma source mass spectrometry and applying these systems to a variety of geological problems. While I enjoy tweaking mass spectrometers, I still like to engage in the more traditional techniques of fieldwork and petrography to complement the isotopic data. Current research interests include:
1) Utilising stable Cr isotopes to investigate the redox state of modern and ancient oceans and the evolution of oxygen in the atmosphere.
2) Using high-precision stable and radiogenic Sr isotopic data to study past ocean chemistry and its relationship to weathering and climate change.
3) Applying Li and Sr isotopes to investigate high temperature isotope fractionation in terrestrial and extraterrestrial materials and associated numerical modelling.
4) The geochemistry and petrology of recent volcanic rocks from the Greater Caucasus in Georgia.
