Awarded the Polar Medal by H.M. the Queen in 2013 for contributions to Arctic and Antarctic science, my principal research addresses the causes and pace of polar ice-sheet change, and the contributions of polar ice sheets to global sea levels. My group and I use a wide array of geophysical, remote sensing and modelling techniques to unravel contemporary glacial change and processes, and to link modern subglacial environments and landforms to the deglaciated landscapes left behind by the retreat of ice sheets across the Northern Hemisphere. Much of my research focus is in West Antarctica, but I also work in the High Arctic.
