Specialties

Glaciology, ice-sheet modeling

Education

Ph.D, Geophysics, University of Washington – 2015

Research Interests

Earth's ice sheets, especially the Greenland Ice Sheet; ice motion and subglacial hydrology; ice fracture, rifting, and crevasse propagation. I study these topics using mathematical modeling, field work, remote-sensing products, and deep learning models.
