Research Interests

I seek to understand volatile element cycling within the Solid Earth. I am interested in how volatiles partition between melts, fluids and crystal phases during melt generation, magma ascent and storage within the crust and how volatile exsolution drives and sustains volcanic eruptions. My research is diverse and includes investigating mantle volatiles; the climate effects of volatile outgassing, the role of volatiles in magma mixing, storage, overturn and eruption; and developing methods to interrogate magmatic and volcanic systems involving ground- and space-based observations of volcanic gases, melt inclusions and crystal stratigraphies. I develop volcano monitoring strategies and instrumentation that feed directly into hazard and risk assessment during volcanic eruptions. 

I am part of a dynamic Volcanology group here at Cambridge with interests in igneous petrology, volcanology, modelling, hazard and instrumentation.

If you are interested in joining our group for postgraduate work, see our advertised projects.

I am Secretary for Science at the Geological Society of London. I am co-chair of the Reservoirs and Fluxes Directorate of the Deep Carbon Observatory and Chair of the DCO Synthesis Group 2019, charged with synthesising and integrating DCO science in the lead-up to the finale of the decadal program in 2019.

Rift volcanism: past, present, future

Continental rift settings, where both effusive and explosive volcanism occur from fissure swarms, volcanic fields and stratovolcanoes, pose a unique set of volcanic hazards. The threat from large magnitude explosions and their associated hazards in rift settings, particularly in the East African Rift, has likely been highly underestimated. Towns and cities in this region are rapidly being developed with little or no regard for the long term risks posed. Cambridge is part of a newly awarded NERC Large Grant to research past and current volcanism and volcanic hazards in the Main Ethiopian Rift. The £3.7 million, five year long project 'RiftVolc'  starts in September 2014 led by Prof Kathy Whaler (Edinburgh) and includes the British Geological Survey, universities of Edinburgh, Bristol, Cambridge, Oxford and Leeds as well as Addis Ababa University and the Geological Survey of Ethiopia.

Centre for the Observation and Modelling of Earthquakes, Volcanoes and Tectonics (COMET)

COMET is a world-leading NERC-funded collaborative centre for understanding tectonic and volcanic processes and hazards through the integrated application of Earth Observation (EO) data, ground-based measurements, and geophysical models. More than 800,000 people have died in earthquakes since the turn of the century; volcanic eruptions have demonstrated their power to cause major disruption to modern society. COMET is a partnership between the universities of Leeds, Glasgow, UCL, Oxford, Cambridge, Bristol and Reading and the British Geological Survey (BGS). We make observations of volcanic eruptions from space and develop integrated models to understand the magma storage and ascent during eruptions incorporating diverse observations and magma properties.
