Physical Oceanographer

British Antarctic Survey


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!

See you at EGU24!

This year I will be returning to Vienna to presenting my work at the EGU 2024 conference. I will be presenting some early work in the OceanBound projct (link here), an ambitious project to rediscover the global ocean through the lens of boundary pressures.

Pre-release of neutralNEMO

About a year ago, I had an idea for a Python package but I couldn’t quite find the time (probably because I was writing a thesis). Either way, I am glad to finally share neutralNEMO with the world.

New position at the British Antarctic Survey

After enjoying a bit of post-PhD relaxation, I have now started as a Physical Oceanographer at the British Antarctic Survey. I am leading the adjoint component of OceanBound, an ambitious project to study the role of ocean boundary pressures in the global ocean.
