Research

My research focuses primarily on the flow and evolution of ice sheets and glaciers. As noted in the most recent IPCC assessment, the single largest uncertainty in projections of sea-level rise over the coming century is due to our as yet inadequate models of cryospheric change, and particularly ice-sheet dynamics. This motivates a great deal of my research effort. More specifically I model the dynamics of ice streams (concentrated regions of fast-flowing ice), along with their floating extensions, called ice shelves. I am also interested in feedbacks between the atmosphere, ocean, and cryosphere, and therefore view the inclusion of dynamic cryospheric component models within earth system models as a priority.
