I am a postdoctoral researcher working on the ice core group at the British Antarctic Survey. My research focuses on using ice core records to reconstruct past environmental changes in polar and sub-polar regions. My approach combines traditional ice chemistry with the novel analysis of insoluble microparticles trapped in the ice to understand the evolution of climate.

1. How Antarctic winds shaped CO₂

   SIWHA investigates how westerly winds and sea ice have influenced CO2 uptake and release in the Southern Ocean.
