Research

My PhD research investigates the potential of ‘blue rings’, a new climate proxy, to reconstruct extreme weather following large volcanic eruptions of the last millennium. My research aims to improve understanding of how these events affected Earth’s climate spatially and temporally, as well as how past societies were impacted.
