My interest in climate science was fostered during the 4 years I spent in Liverpool, studying the physical and biogeochemical processes that drive interactions between the tightly-coupled ocean and atmosphere systems.

My fascination with the ocean has been stoked by an active passion for scuba diving, which I have developed over the last 13 years. I am a PADI certified Divemaster, and have been lucky enough to amass 150+ dives in some of the most pristine marine areas around the world. From underground cave systems in Mexico and the Blue Hole in Belize, to volcanic seamounts in Borneo and coral reefs in Indonesia, I have seen the beauty that lies beneath the surface of the ocean and the increasingly inescapable impacts of anthropogenically-driven climate change.

My PhD research at the University of Exeter was in partnership with the Met Office, the Plymouth Marine Laboratory (PML), and the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO). This project addressed the oceanic concentration of dimethylsulfide (DMS), its sea-to-air transfer, and the subsequent impacts upon aerosols, clouds and the global radiation balance. This work helps to reduce model uncertainty surrounding DMS emissions, which have a large impact on aerosol radiative forcing and climate sensitivity to anthropogenic emissions.
