I am a professor of volcanology. Drawing on expertise in volcanology and magmatism, atmospheric chemistry and paleoclimatology-stratigraphy, my work investigates volcanic behavior across multiple timescales. I am a 2010 Philip Leverhulme Prize Winner.

My motivation is to understand volcanoes as a key planetary scale process throughout geological time, vital for maintaining habitability as well as driving environmental change, analyse natural hazards and geothermal developments.
