Research Highlights

Glacial GeomorphologyDigital elevation model of subglacial bedforms (drumlins)

I am interested in the formation of subglacial bedforms, the landforms which are produced at the sole of a glacier or ice sheet. My research led to the confirmation of a long held (40 year!) hypothesis that subglacial bedforms belong to a morphological continuum. I have also dug holes into subglacial bedforms, and flown UAVs over them in order to work out how they form. I am also interested in the formation of meltwater related landforms.

Palaeo-ice sheets Outline of the extent of the last British-Irish Ice Sheet

The action of the ice sheets which existed during the last ice age can be deciphered from the landforms and sediments they left behind. I am currently employed on BRITICE-CHRONO, where my job is to make numerical ice sheet models interact with data pertaining to the last ice sheet to cover Britain and Ireland. I am also interested in the glaciation of Alaska.

Ice Sheet SurfacesThe surface of Byrd Glacier, Antarctica

The surfaces of ice sheets display many features which can tell us about the nature and history of ice flow. My research uses extensive mapping of the surface of Antarctica, combined with geophysical data of ice sheet conditions, in order to understand how these beautiful ice-scapes form.

Supra-glacial hydrology of AntarcticaWater moving across the surface of the Antarctic Ice Sheet

I was part of the team which discovered the widespread occurrence of meltwater streams on the surface of Antarctica. This surprising discovery has large implications for the future of the ice sheets in Antarctica. Future work will help understand how these systems evolve, and the impact they have on ice sheet dynamics.
