Alun is a glaciologist with interests in subglacial processes, ice / methane-hydrate interactions and the dynamical response of glaciers and ice sheets to atmospheric, oceanic and geological forcing. He holds an independent Arctic Five research professorship to address the long-term stability and environmental legacy of the cryosphere and its impact on global sea-level, the carbon-cycle, and broader impacts on society and landscape. His approach uses novel field-data to improve process understanding and constrain models with live projects across the Arctic, specifically focus on Greenland, Alaska and the Barents but he also works in Patagonia, Alaska, Asia and Antarctica. He has led over 60 successful research/exploration expeditions (without mishap!) across icy regions of the planet, many independently from his own sailboat and helicopter logistics non-profit company.
