Volcano Petrology and Igneous Geology

My research concerns the generation, movement and evolution of magma within the Earth. I use a combination of igneous petrology, high temperature and pressure experimental geochemistry, thermodynamics and field geology to address the fundamental problem of how volcanoes work.

Of particular interest are processes associated with magmatism at destructive plate boundaries (subduction zones), which host many of the world’s most explosive volcanoes. I am currently involved in research projects at several active subduction zone volcanoes in the USA (Mount St. Helens), Lesser Antilles, Mexico (Volcán Colima and Nevado de Toluca), New Zealand and Kamchatka, as well as the Afar region of Ethiopia, an area of active continental rifting. I am also working on an industry funded project (BHP Billiton) to investigate the generation of porphyry copper ore deposits from the perspective of petrology and volacnology.
