Research Overview

My research focuses on crystal specific studies (in particular, in-situ microanalytical approaches) in order to determine the pre-eruptive state of volcanic plumbing systems and the timing of magmatic processes. This includes the use of in-situ major and trace elements to determine magmatic storage conditions and establishing the timescales involved through U-Pb dating of zircons and diffusion modeling.

I have worked on the products of supereruptions in New Zealand to determine the magmatic processes which lead to such large scale silicic eruptions. I have also investigated processes in the deeper magmatic plumbing systems beneath the islands of the Lesser Antilles Volcanic Arc through the study of erupted plutonic xenoliths/cumulates.

My research is currently focussed on volatile recycling at the Lesser Antilles Arc. In particular, using trapped aliquots of magma (melt inclusions) to determine the sources and pathways of fluids.
