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.


I studied for a BA degree in Geology at University College, Oxford University (1983) and for a PhD in Earth Sciences at Trinity Hall, Cambridge University (1989). My PhD project concerned the Adamello granite batholith in the Italian Alps, and was supervised by Professor Steve Sparks. While a PhD student I spent two years as a Kennedy Memorial Scholar at Massachusetts Institute of Technology (1985-87). I came to Bristol in 1989, where I have been ever since, apart from brief spells as a Junior Research Fellow at Hertford College, Oxford University (1990-91), a Fulbright Scholar at University of Oregon (1998-99), a Guest Professor at Nagoya University, Japan (2007) and a Moore Scholar at the California Institute of Technology (2014 and 2016). At Bristol I held research fellowships from the Royal Society and NERC for 16 consecutive years (1991-2007). I was briefly Head of School of Earth Sciences (2008-09 and 2018). In 2008 I was elected a Fellow of the Royal Society and in 2011 Member of the Academia Europea.


I teach an igneous petrology class to third and fourth year students.
