Igneous Petrology


Originally from Glasgow, his interests in Physics and Geology have taken him to degrees and jobs in Cambridge, Paris and Edinburgh. His approach combines robust fieldwork, leading-edge microanalysis and computational techniques to provide a quantitative understanding of magmatic processes. Iceland has provided a natural focus for much of this work and provides a platform for a global view of magmatism at spreading ridges, ocean islands and large igneous provinces.
