I am a senior research scientist in the marine systems modelling group at NOC with a background in observational marine biogeochemistry. My research aims to improve our understanding of ocean carbon sequestration, with a particular focus on the biological carbon pump and the efficacy, viability and environmental and socio-economic impacts of marine carbon dioxide removal approaches. I utilise my observation-modelling skillset to explore the biogeochemical and physical controls on carbon export, sinking particle transformation and the fate of remineralised carbon to understand the implications for future carbon storage due to climatic change and human interventions.

Some specific topics and projects that I am or have recently worked on are listed below:

• The North Atlantic carbon cycle in global ocean biogeochemical models, including CMIP6 models (BRICS project)
• Lagrangian particle tracking with biogeochemical applications, including assessing marine carbon dioxide removal approaches (CLASS and AtlantiS projects)
• Linking environmental impacts of marine carbon dioxide removal with socio-economic indicators (AtlantiS project)
• Deep ocean carbon sequestration and storage efficiency (CLASS project)
• Marine snow composition, formation and transformation, with a current focus on the drivers of aggregation including the role of transparent exopolymer particles (TEP; PARTITRICS project)
• Assessing the potential drivers of nutrient trapping in the Southern Ocean using CMIP6 models (BIOPOLE project)
