Assistant Professor of Earth and Planetary Sciences
Research interests include the formation and interior evolution of the Earth and other planetary bodies. Roger's primary tool is paleomagnetism, which he complements with geodynamical modeling.

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 observations with numerical models to constrain these dynamic topography signals and remove them from palaeo sea-level estimates. These revised values will serve as useful tie points to calibrate ice sheet models, reducing uncertainty in projections of future sea-level rise.
