Summary

Julia is a volcanologist specialising in explosive volcanic eruptions, specifically volcanic stratigraphy, tephrochronology, the petrology of eruption deposits and volcanic hazards. Her PhD, at the University of Leeds, focused on the petrological and geochemical evolution of the Colima Volcanic Complex, Mexico which involved detailed mapping and stratigraphic correlation of explosive eruption deposits (specifically tephra fall), and sampling for petrological and geochemical analysis, and grain size distribution. Recently Julia has been carrying out volcanic hazard analyses in Ascension Island, Mexico and Ethiopia using a scenario-based approach, and expert elicitation to determine frequency, magnitude and likelihoods of potential future eruptions. Her main interests lie in volcanic hazards and impacts of volcanic eruptions on all scales, from local communities to national (systemic vulnerability) and global.
