My main research interest lies in explosive eruptions, specifically studying the tephrochronology in combination with petrology and geochemistry of eruptive products in order to determine the past behaviour, and therefore potential future behaviour, of the volcano. My PhD focused on the Holocene evolution of the Colima Volcanic Complex, Mexico. I have carried out field mapping in Peru, Ecuador, Mexico, Armenia and Tanzania. Recently I have been working on the impacts of volcanic eruptions and science communication.
