I am a geophysicist whose primary research interest is polar glaciology and the application of mathematical models to understanding mesoscale phenomena in the Antarctic ice sheet system. I am lead investigator for the NZARI-funded "Vulnerability of the Ross Ice Shelf in a Warming World", an ambitious multi-institution, interdisciplinary effort to observe and understand processes and process interactions that determine thresholds for and rates of change in a region of great national and international concern.
