I am interested in internally and externally-driven ocean biogeochemical feedbacks and climate system thresholds. I use intermediate-complexity climate models to test representations of marine biogeochemistry and phytoplankton ecology with the objective of cost-effectively simulating their influence on climate over a variety of timescales. My current work explores model structural uncertainty using parameter optimisation methods, the role of calcifier-diatom competition in climate over glacial timescales, greenhouse climate and biogeochemical dynamics, and the fate and transport of microplastic via biological pathways and biogeochemical effects. I am an expert in modelling the role of marine ecology in global biogeochemical cycles and in simulating the response of ocean primary production to climate change and microplastic.
