BIO

Some of the least understood regions of the deep Earth lie beneath the East Antarctic Ice sheets. The structure and material properties of the lithosphere and asthenosphere provide an important control on the process of Glacial Isostatic Adjustment - the response of the solid Earth and mantle to changes in ice sheet mass on the Earth’s surface. A solid understanding of glacial isostatic adjustment is necessary in order to constrain both predictive models and observational estimates of ice loss, and hence improve projections of future sea level rise.

Detailed studies of 3D Earth structure in East Antarctica are challenging due to the sparsity of seismic stations across this region. My project makes use of stochastic approaches to inversion and techniques in single station seismology to constrain the rheology of the lithosphere and asthenosphere in key regions around East Antarctica. This work aims to improve our understanding of earth structure in regions of Antarctica containing few seismic stations, and will help to inform future models of sea level change.
