Overview
I am a post doc working with James Screen on the ArctiCONNECT project. My aim is to investigate the mechanisms through which Arctic amplification may have an effect on weather and climate in the mid-latitudes.
Before arriving in Exeter, I completed a DPhil in Atmospheric, Oceanic and Planetary Physics at the University of Oxford under the supervision of Prof. Peter Read. The topic of my thesis was atmospheric circulation on slowly rotating planets (e.g., Venus, Titan) and extrasolar planets. Prior to this, I did my undergraduate degree in Mathematics here in Exeter.
