Biography

My research interests are in glacial and glacially-influenced sedimentation and geomorphology, Quaternary geology, and high-latitude glaciated environments. A central theme is the reconstruction of Quaternary ice-masses and their dynamics from geological and geophysical evidence in both marine and terrestrial settings. My research has evolved from an initial focus on terrestrially-based investigations of glacigenic sediments and landforms to larger-scale marine geology and geophysics-based reconstructions. I have worked either from ship or on land in various regions of the Arctic (Canadian Arctic islands, Greenland, Norwegian-Greenland Sea) and Antarctica, the Irish and Celtic seas, and the Canadian Prairies. The underlying theme of my research is ice-sheet reconstruction from geological and geophysical evidence, and the use of modern glacial analogues to better understand the geological record. My current research interests can be summarised as:

1. Marine geophysical & geological investigations of glacier-influenced sedimentation and ice sheet history on polar continental margins including Greenland and Antarctica.

2. Investigating physical processes at palaeo-ice-stream beds.

3. Reconstructing the Late Quaternary history of the last British-Irish Ice Sheet.

I have been awarded the Lewis Penny Medal by the Quaternary Research Association (2005) and the Lyell Fund (2009) by the Geological Society of London in recognition of my research.
