Short presentation
My research investigates the Greenland and Antarctic ice sheets, along with mountain glaciers in the Arctic and High Mountain Asia. It centres on two main areas: (1) inferring glacier basal conditions and ice thickness to spin up ice-flow models, and (2) modelling mass balance and firn processes to improve our understanding of how glaciers and ice sheets respond to a changing climate.
