Personal profile

Research interests

I look at what drives the marine ecosystem, biogeochemical cycles and climate to interact. I am interested in particular in the role of marine plankton and nutrients on the carbon cycle. My work combines mathematical and numerical modelling in comparison with observations.

Recent projects have focused on understanding the controlling mechanisms for diatom and coccolithophore ecology, marine nitrogen fixation and the spread of anoxic conditions during the Oceanic Anoxic Events of the Cretaceous.

  • Exploring the diatom diversity on the carbon cycle: I look at the effect of size and density in cells of diatoms on the export of organic carbon particles  


  • Diversity of coccolithophores: I test different ecological trade-offs for a diverse population of coccolithophore to analyse the causes and consequences of diversity and calcification on the carbon cycle and climate in the global ocean. I have recently started using statistical data to determine the key traits driving coccolithophore ecology


  • Cretaceous Oceanic Anoxic Events (OAEs): I analyse the interactions between the nutrient cycles (phosphorus, nitrogen and iron), climate and the cycling of carbon, oxygen and sulphur in an Earth System model (GENIE). In doing so, I evaluate the sensitivity of marine biogeochemistry to warming, increased stratification and decreased dissolved oxygen concentration.


  • Marine nitrogen cycle: I investigate how the marine nitrogen cycle (including nitrogen fixation, denitrification and nitrification) can regulate marine productivity and thus climate for modern (using MITgcm) and past climates (using GENIE).


  • Diversity of nitrogen fixers: Using a self-assembling ecosystem model (Darwin project), I reconstruct diverse population of nitrogen fixers of the modern ocean to assess the impact of diversity on the nitrogen cycle and climate.
