Curriculum Vitae:

Nicole-Jeanne Schlegel

Dr. Nicole-Jeanne Schlegel is a Scientist at the NASA Jet Propulsion Laboratory in the Sea Level and Ice Group. She is a a member of the Ice Sheet System Model team, working to assess uncertainties in ice sheet model projections, particularly on the Greenland Ice Sheet, as a result of errors in climate forcing. Her other research interests include the use of NASA remote sensing observations to better constrain uncertainty in model simulations and ultimately, to determine the mechanisms, physical processes, and timescales most responsible for current changes in ice sheet dynamics and mass balance. Before pursuing her PhD, she worked at Raytheon Company, designing software for training simulations. During her PhD studies, she worked with glaciologist Kurt Cuffey at the University of California, Berkeley, and climatologist Norman Miller at the Lawrence Berkeley National Labs. She participated in regional climate model-based studies of California climate change and extreme weather events, and her PhD focused on continental-scale modeling of the Greenland Ice Sheet and investigating its present and future sensitivity to changes in surface mass balance.
