Biography

Ship-based investigations to reconstruct Greenland Ice Sheet history

I am a glacial geologist and Quaternary scientist, interested in glacial and glacially-influenced sedimentation and the reconstruction of ice sheets. I have a background in glacial sedimentology, initially from terrestrial glacigenic envronments but subsequently evolving into the use of marine geology and geophysics to reconstruct ice sheet behaviour and sedimentation. I have worked extensively in the polar regions, in both the Arctic (Greenland, Arctic Canada, Svalbard, Norwegian-Greenland Sea) and Antarctic. I also have a long-standing active research interest spanning several decades in the history of the last British-Irish Ice Sheet. The central theme of my research is ice-sheet reconstruction from geological, geomorphological and geophysical evidence. 

I have been awarded the Lewis Penny Medal by the Quaternary Research Association and the Lyell Fund by the Geological Society. I am currently an Editor for the journal Quaternary Science Reviews and previously have been an Editor for The Cryosphere. I am the Geology representative for the RRS Sir David Attenborough Science Commisioning Group.
