I am interested in understanding the surface expression of deep Earth dynamics and structure. My past research has focused on constraining and modelling the impacts of mantle convection on surface elevations and landscape evolution. This work has helped to reconcile numerical models and observations of this so-called ‘dynamic’ topography, while revealing that convectively driven vertical motions may occur at rates of up to 100 m per million years. These fast-evolving perturbations have significant implications across the Earth Sciences as they may destabilise polar ice sheets, alter ocean circulation via closure of ocean gateways, and control locations of resource-bearing sedimentary basins. My current work aims to integrate geological and geophysical observations with numerical models to better constrain dynamic topography and glacial isostatic adjustment in order to assess their impact on polar ice mass change and palaeo-sea level estimates. These outputs will serve as useful tie points to calibrate ice sheet models, reducing uncertainty in projections of future sea-level rise.
Topics of Interest:
Mantle dynamics, glacial isostatic adjustment, marine geophysics, geology, sea-level change, ice dynamics, palaeoclimate, mineral resources, inverse theory, igneous and metamorphic petrology, geomorphology, basin analysis, stratigraphy.
