Research

I am interested in investigating ice sheet dynamics through passive seismological techniques. As glaciers move, a variety of seismic signals are produced which can be used to infer properties of the ice and bedrock underneath it. My current research focuses on resolving the basal hydrological properties of Store Glacier in Greenland, using a network of geophones deployed on the surface and in boreholes. This work is part of the ERC-funded RESPONDER project.

In the past, my research has also focused on

  • constraining the influence of mantle convective processes on the lithosphere of the North Atlantic region using receiver function analysis
  • investigating the significance of the Saffman-Taylor instability in determining the planform shape of the Icelandic mantle plume (see New Scientist article)
  • locating magma migration prior to the 2010 eruption of Eyjafjallajökull volcano, Iceland, using microseismic signals
