My research interests are in the use of satellite and airborne remote sensing techniques, integrated with in situ observations and modeling, to understand changes in the Earth System, with a primary focus on the Earth's ice cover. In particular, my research focuses on the contributions of ice sheets and high-latitude glaciers to sea level rise and their relationship to the changing climate. Toward that end, I have been heavily involved in the development of NASA's Ice Cloud and land Elevation Satellite (ICESat) and its successor, ICESat-2, and I have worked on cryospheric applications of various other satellites and aircraft instruments. I also continue to be consulted by NASA and other organizations for my perspectives on space-based science missions and NASA organizational and project-management matters.
