I am a seismologist interested in global and local seismic phenomena which allow us to understand better how the Earth works, including how the interior of the Earth moves around, where and how molten material is created, and the history of our planet.
My experience includes the observation and modelling of the effects of seismic anisotropy—the variation of properties with direction—to infer deformation, encompassing mineral physics, seismic wave propagation and geodynamics. I am also interested in microseismicity in rift settings (Ethiopia and Iceland) and shallow reservoirs (geothermal and petroleum), and how earthquakes occur in the Earth's transition zone.
I am currently a Leverhulme Early Career Fellow, and my project (‘The Secret History of the Earth’s Mantle’) aims to investigate the structure of the lowermost mantle. I am also part of the NERC-funded ‘Superplumes, Superpiles, Superpuddings’ project, which aims to determine whether observations of the Earth’s structure are compatible with current models of Earth formation. I am an associate fellow in the ‘Volatile Legacy of the Earth’ consortium within the NERC ‘Deep Volatiles’ programme, and an associate within ‘COMET’.
