Research interests
Tom is a remote-sensing glaciologist with an interest in how glaciers and ice sheets have responded to environmental change. He uses data acquired by satellites, aircrafts and drones to quantify ice-mass extent, structural evolution, debris-cover changes and glacier dynamics. He has published works relating to glacial changes in Antarctica, Greenland, the High-Arctic (Russia, Svalbard, Canada), the European Alps and Patagonia. Current research projects continue his long-standing interests in Antarctic Ice Shelf disintegration, as well as long-term changes to glacier systems in the Swiss Alps, the structural controls on Himalayan glacier recession, and the reconstruction of Earth's former ice sheets from landform evidence.
