Research interests

My major interests are the geochemistry of volcanic systems and applying high-resolution isotope analysis to understand geological and anthropogenic problems. I have worked in a diversity of magmatic environments, including ophiolite geology, subduction zone volcanism, boninite petrogenesis, ocean island hot-spot activity and continental rift zone magmatism. In the laboratory I have developed novel analytical techniques to measure hafnium, uranium, plutonium and lead isotopes by mass spectrometry.

Currently I am investigating:

· Chemostratigraphy of phonolitic volcanoes to examine pulsation in the Earth’s mantle;

· Magma chamber dynamics and the causes of major volcanic eruptions;

· Tracing the origin of ceramic artefacts using high-resolution Pb isotopes;

· Isotope geology of uranium ore deposits.
