My primary interest is the geochemistry of geological and environmental samples (i.e. rocks & sediments) and what geochemistry can tell us about elemental cycling within the earth system. The geochemistry utilised as a part of this work includes traditional major and trace element analysis as well as stable (13C, 34S, 56Fe) and radiogenic isotopes (U/Pb, Sm/Nd, Rb/Sr). My work to date has focussed on large igneous provinces and links to climate, nutrient availability and primary productivity.

I currently have oportunties for two PhD students, the projects are:
- Geochemistry of Precambrian ocean island basalts. This project seeks to identify Precambrian OIB occurrences and build a record of oceanic flood volcanism to compliment the existing continental flood basalt record. Ultimately this project seeks to improve our understanding of the geodynamic and environmental impact of flood volcansim in the Precambrian.
- Geochemistry of black shales from Mesoproterozoic basins utilising major, trace and Nd isotopes to investiagate the role of magmatism plays in driving nutrient availbility and primary productivity.
