Research Themes & Scholarly Interests

My research focuses on understanding the processes controlling ice flow in Antarctica, with the goal of improving computer model predictions of the continent’s contribution to future sea level rise. I have a particular interest in how ocean tides affect the ice sheet and how we can use observations of these tidal effects to gain insights into ice rheology and flow. 

Current/Recent Projects

Filchner Ice Shelf System, NERC large grant, Post-doctoral research fellow, 2015 –

‘Satellite observation and model intercomparison of tidal processes in ice-sheet grounding zones’. 2015 SCAR fellowship in collaboration with the University of Canterbury and Gateway Antarctica
