My undergraduate, postgraduate and postdoctoral research has a strong foundation in ecosystem physiology and the geosciences (The University of Edinburgh). I have worked alongside experimentalists and modellers to develop theoretical understanding of stable isotope fractionation in a range of ecological systems in order to interpret the responses of ecosystem components to climate, holding positions at the University of Cambridge before joining the Institut National de la Recherche Agronomique (Bordeaux) in 2012 and building the ECOFUN team with colleagues https://www.bordeaux.inra.fr/ispa-ecofun/wordpress/. My current research lies at the interface between geochemistry, physics, biology and ecology, and aims to describe regulation of atmospheric CO2 and COS concentrations at scales spanning the enzyme to the globe.
