Research Interests

All aspects of volcanology from the communication of hazards associated with volcanic eruptions to the ways in which magma is stored prior to eruption. Current research includes: the degassing of bromine and iodine from volcanoes and its impact on the atmosphere; the interaction between rainfall and volcanic activity (both lahars and primary activity); pre-eruptive storage conditions in the Aegean and Vanuatuan arcs; the communication of volcanic hazards in the Caribbean and the use of tephra as a marker of landscape change in the Mediterranean


Biography

My background is in Geology, with a first degree from the University of Edinburgh and PhD from the University of Bristol. My real passion within geology is Volcanology. My PhD looked at several aspects of the degassing process associated with silicic volcanoes. My first post-doctoral research project in 1996 involved an experimental investigation of the magma storage conditions of the newly erupting Soufriere Hills Volcano and as well as two further post-doctoral positions (Postdoctoral Fellow at the University of California, Berkeley and Maitre Assistante at the University of Geneva) I also undertook several periods as a duty scientist at the Montserrat Volcano Observatory. My experiences on Montserrat and elsewhere convinced me of the need for a truly inter-disciplinary approach in order to properly understand volcanic eruptions and mitigate their impact. Since my appointment at UEA in 1999, I have made full use of the rich diversity of researchers at UEA that go beyond the usual realms of geology and collaborate with sedimentologists, atmospheric scientists, geophysicists and social scientists on a variety of different problems relating to volcanic phenomena.
