My present research covers a range of volcanic phenomena that I summarise here. For more information please see my publications here or on ResearcherID, or get in touch.

Identifying the fluid dynamic sources of seismic and acoustic signals at volcanoes that result from flow processes forms a large component of my research. The motivation here is to improve forecasting of volcanic events by establishing a link between flow within volcanic conduits and the ground displacements generated by those flows. Stromboli forms the focus of current efforts because of the high quality and large quantity of field data available. The analogue approach is used to characterise pressure and force changes as gas escapes from liquid within an experimental system. The analogue data can be compared with field measurement and numerical experiment to gain insight into fluid flow sources of seismic and acoustic phenomena.

The transport of fine volcanic ash in Earth's atmosphere is heavily influenced by the aggregation of ash particles into larger clusters, a process that significantly changes aerodynamic behaviour. Understanding aggregation is key to predicting the atmospheric transport of volcanic ash and, therefore, managing the impacts of ash on air transport.

The Martian crust is water-rich to depths of about 10 km, with a frozen cryosphere overlying an aquifer of possibly planet-wide extent. The intrusion of magma into the upper Martian crust is likely to be accompanied by a range of physical processes as ice melts, water vaporises and compounds dissociate to generate surface topography. Identifying the dominant processes will give insight into the nature of the Martian cryosphere, aquifer and crust, as well as provide analogous insight into the consequences of magma intrusion into Earth's crust.
