Understanding volatile behaviour from the source regions of magma deep in the Earth to eruptions at the surface.

Research Interests

My research encompasses igneous petrology, geochemistry and volcanology. I specialise in the use of in-situ micro-analytical techniques to measure the compositions of volcanic rocks, glass, minerals and inclusions of melt trapped inside minerals. I am particularly interested in quantifying volatiles to understand mantle volatile cycles and the role volatiles play in magmatic processes, from mantle melting through to eruption. I work with samples from a variety of tectonic settings ranging from basalt to rhyolite in composition. Samples are often collected from volcanoes that erupted under water or ice so that they retain magmatic volatiles. I am involved in the international scientific ocean drilling programme, having participated in two expeditions.
