I study the dynamics of volcanic processes using a combination of laboratory experiments, theoretical fluid mechanics, fieldwork and petrology. Current projects include the effects of crystals and bubbles on magma convection, the origins of acoustic and seismic oscillations at volcanoes, and mechanisms and consequences of gas movement through magmas.

My research is motivated by volcanic problems but there are broader applications. I like to work with geoscientists, mathematicians and engineers to explore connections between environmental, geophysical and industrial issues.
