Profile
Research
I study the generation, emplacement and hazard associated with pyroclastic rocks. I use a variety of techniques including field work, analytical work, numerical modeling and statistics to answer outstanding questions about these complex and potentially devastating phenomena. I have worked on the eruption dynamics of peralkaline rhyolite volcanoes in Ethiopia, statistical estimation of probabilistic hazard associated with pyroclastic density currents, and I have experience working alongside volcano monitoring operations in Vanuatu, New Zealand and Ethiopia. Currently I study suevite: a type of rock left behind during catastrophic bolide (meteorite/asteroid etc.) impacts, which bear a striking resemblance, and may be emplaced in a similar manner to its volcanic equivalent known as 'ignimbrite'. In short, I'm trying to answer the question: "How is impact melt fragmented and emplaced, and what does this tell us about the process of bolide impact?”
