I am a glacial geologist and glaciologist whose research interests include reconstructing and understanding ice sheet dynamics and subglacial processes from geological and geophysical evidence in both marine and terrestrial environments. They can be summarised as follows: Investigating the drainage and storage of meltwater through palaeo- and contemporary ice sheets. The identification and investigation of landform-sediment assemblages and physical processes at the bed of palaeo-ice streams, and the controls governing their retreat. Reconstructing the Late Quaternary history and dynamics of the last British-Irish Ice Sheet.
