Poul Christofferson is a glaciologist at the University of Cambridge. His research focuses on ice sheet dynamics, specifically ice sheet interactions with the atmosphere and oceans. His research spans scales, from whole glaciers and ice sheets to micro-scale studies of processes observable in a borehole. Part of his research group develops observational understanding of Earth's glaciated environment using autonomous drones and radar systems, seismology, and records from boreholes drilled to the base of fast-flowing glaciers. Another part of his research group integrates those observations as constraints for numerical models, thereby improving the models.
Christofferson is a lead principal investigator on the TIME project. He and his team will use a variety of techniques, such as radar and seismic analysis, to understand the margins of the Thwaites Glacier, investigating what controls its width and speed.
