I am a postdoctoral research associate in climate-modelling working with Dr Anja Schmidt in the Centre for Atmospheric Science. My research focuses on understanding how large-magnitude volcanic eruptions impact the Earth’s climate. I am particularly interested in how different properties of an eruption such as the amount of sulfur dioxide emitted, the eruption latitude and the emission altitude impact the climatic response, and how sulfate measured in ice cores can be used to estimate the climatic response of historic eruptions. I am currently working on using the new UK Earth System Model to simulate eruptions over the last millennium to better understand their impact on climate variability.
