My CV.

Research Interests

My research centres on the cycling of volatiles between the atmosphere and the mantle and the role that magmatic volatiles play in melting, magma genesis, storage and transport, volcanic eruption style and climate modulation over a range of timescales. I am an observationalist who develops quantitative frameworks to understand complex physical and geochemical datasets in collaboration with a diverse range of geochemists, geophysicists and volcanologists. My early career was spent in volcano observatories working on volcano hazard assessment, where I played a role in developing new instrumentation to monitor eruptions. I am co-Chair of the Reservoirs and Fluxes Directorate of the Deep Carbon Observatory and Chair of the Synthesis Group 2019, charged with synthesising and integrating DCO science in the lead-up to the finale of the decadal program in 2019. I am an enthusiastic communicator of science and enjoy giving public lectures on the subject of volcanology and natural hazards. I am part of a dynamic Volcanology group in Cambridge with interests in igneous petrology, volcanology, modelling, hazard and instrumentation. If you are interested in joining our group for postgraduate work, see our advertised projects


  • Magma mixing and ascent
  • Volcanology
  • Volatile geochemical cycling
