  • Brief Bio

    My scientific research expertise is in remote sensing and modeling of Earth’s ice sheets, with the goal of improving projections of sea-level rise. The goal of my current research is to develop calibrated probabilistic projections of the sea-level contribution from the Greenland Ice Sheet under various warming scenarios. I have a broad background and leadership experience in scientific research and engineering, including management of a NASA satellite ground system software development task, supervision of undergraduate researchers, and participation in community-wide efforts, with an organizational role as a member of the Greenland Ocean Forcing Working Group for the Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6), and as a data contributor to the Ice-sheet Mass Balance Intercomparison Exercise (IMBIE).
