My research interests are in the use of satellite and airborne remote sensing techniques, integrated with in situ observations and modeling, to understand how and why the Earth's ice cover is changing, and what those changes mean for life on Earth. 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.
