My research interests and activities are multidisciplinary, involving atmospheric science, remote sensing, and glaciology.  In particular, my work involves instrument development, conducting airborne and surface-based field experiments (mainly in Greenland and Antarctica), and validating the field measurements using ice core analyses, snow pit data sets and numerical weather forecast model data.  Most of my current research is related to the study of ice sheet response to global warming, the current mass balance of the ice sheets, and the contribution of the Greenland and Antarctic ice sheets to sea level rise.  This research has a high degree of societal relevance, as our work has estimated that a 1 meter rise in sea level would displace more than 100 million people worldwide.
