I study the dynamics of ice streams and outlet glaciers. My primary interest is understanding how recent changes to large outlet glaciers will propagate upstream. Future sea level rise from the ice sheets, particularly from Antarctica, will largely be determined by how quickly changes initiated by a warming ocean will affect currently stable, inland ice. I investigate modern changes directly, but also try to contextualize current retreat by understanding past ice flow. My work involves numerical models, remote sensing, and field data, particularly ice-penetrating radar, depending on the glaciological question.
