Julia is a volcanologist specialising in explosive volcanic eruptions and associated hazards and impacts on all scales, from local communities to national and global. Her main interests lie in understanding hazard interactions and the unfolding impacts on communities and the built environment. In particular, Julia is interested in the communication and translation of complex science to support decision-making. Julia recent research focuses on the implications of volcanic hazards on international tourists; physical vulnerability of buildings to tephra fall, and exploring cause-and-effect relationships during multi-hazard events.
