Research overview

The motivation for my research is to understand how the interior of a planet affects and controls the composition of its surface, and how volcanic degassing relates to long-term habitability. My research combines isotopic and petrological investigations of natural samples alongside high-pressure and high-temperature experimental and theoretical projects. My main aims are to use isotopic and thermodynamic constraints to understand volatile cycling in to and out of planets. I primarily apply these geochemical tools to understand the pathways followed by volatile elements subducted into terrestrial mantle over geological timescales, with a strong emphasis on constraining the origin(s) of diamond-forming carbon in the mantle, and the nature of the geodynamic volatile cycle(s).

Prior to St Andrews I spent 2 years as a Carnegie Postodctoral Fellow (Geophyscial Laboratory, 2011-13) before short postdoc positions at Edinburgh (2013-14) and Bristol (2014-15). I hold a BSc in Geology (Kingston, 2003-06), MSc in Isotope Geochemistry (Royal Holloway, 2006-07), PhD in Petrology and Stable Isotope Geochemistry (UCL, 2008-11).
