destructive plate boundaries
Areas of expertise
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 , 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.
Currently I am involved in research projects at several active volcanoes in the USA (Mount St. Helens), Mexico (Volcán Colima and Nevados de Toluca) and the Afar region of Ethiopia, an area of active continental rifting.
