I use numerical models to simulate the Antarctic ice sheet both at the continental scale and at the scale of individual outlet glaciers. My interest lies in understanding how the ice sheet responds to changes in climate, and to do that we use geological evidence of past changes together with a process understanding of the modern system. Much of my work employs the Parallel Ice Sheet Model (PISM), developed jointly by the University of Alaska, Fairbanks, and Potsdam Institute for Climate Research.
