I am an Associate Professor at the University of Southampton and a Fellow of the Turing Institute, the UK’s national institute for data science and artifical intelligence. My research explores the major controls on Earth surface conditions over geologic time. This includes the effects of tectonic, volcanic, sedimentary, and metamorphic processes; their interactions, and how these shape the biosphere and climate system over different timescales.

Over the past ten years, I have supervised 14 PhD students (ten to completion and four in progress), six of these as lead supervisor, and 3 PDRAs. Over the same period, I have supervised 20 MSci research projects, 5 of which have led to publications in leading international journals (GRL, Lithos, Geology, Scientific Reports, Bulletin of Volcanology).
