I am a postdoctoral researcher in the Modelling Group of the Ice Dynamics and Paleoclimate team. I am also an affiliate of Downing College, Cambridge. I am currently working with Dr Rosie Williams and Dr Rob Arthern on the ENSOWAIS project, which aims to quantify the retreat of Western Antarctica in the context of El Niño–Southern Oscillation variability.
Before moving to BAS, I completed undergraduate, masters and doctoral degrees in Mathematics at the University of Oxford. I completed my dPhil in 2020, under the supervision of Prof. Dominic Vella and Prof. Ian Hewitt.
Below is a brief list of my research interests. For more information, see my personal website [coming soon]
- Sea level rise: How can we improve predictions of sea level rise in the next century? To what extent is the El Niño–Southern Oscillation responsible for the current trends in ice loss from Antarctica?
- Geometric controls on melting: How, and why, does the geometry of cavities under ice shelves control melt rates? Can we develop parametrizations of melt rate that account for cavity geometry?
- Ice sheet modelling: How can we improve the speed and fidelity of the current generation of ice sheet models?
I also am a lead developer of the BAS ice sheet model “WAVI” [public release coming soon], a fast and friendly ice sheet model, written in Julia.
