Bio

I am a physical oceanographer at the British Antarctic Survey and I study basin-scale and global-scale circulations alongside their behaviours in climate models.

I lead the adjoint component of OceanBound, an ambitious project to study the role of ocean boundary pressures in the global ocean. As an adjoint modeller, I am using the ECCO state estimate to determine what external forces the boundary pressures are most sensitive to.

I completed my PhD at the University of Oxford in 2023. I studied the dynamics of the Weddell Gyre and its influence on Southern Ocean ventilation. I tackled this research by designing idealized models, developing diagnostic methods, analyzing Lagrangian trajectories, and exploring possibilities with pen and paper analysis. I continue to study the dynamics of the Weddell Gyre and enjoy a close collaboration with members of the SO-CHIC project (Southern Ocean-Carbon and Heat Impact on Climate).

Please reach out to me if you would like to meet or collaborate!

Announcing the GOCC meeting

I am excited to announce the very first Global Ocean Circulation and Connectivity (GOCC) meeting. The meeting will take place on Monday 7th September 2026 at Bangor University’s School of Ocean Sciences (the same week as the Challenger 2026 conference) and will provisionally run from 10:00-17:00 BST.

SNAP Seminar on 23rd March

On Monday 23rd March at 16:00 GMT, I will be giving a virtual seminar as part of the SNAP seminar series. The seminar will be an in-depth investigation of the atmospheric drivers of basin-wide geostrophic transport in the Atlantic using OceanBound’s adjoint modelling framework.
