Matthew Siegfried is a glaciologist who uses satellite remote sensing techniques in combination with field-based and airborne geophysical methods to understand physical processes of Earth’s glaciers and ice sheets. His research interests include the role of dynamic subglacial hydrology, interactions between ice, ocean, and solid earth, adapting field geophysical methods for ice-sheet applications, and independent validation of remotely sensed observations. Matt has completed field work on three continents including eight expeditions to Antarctica, conducting experiments ranging from geochemical sampling of hydrothermal systems to ground-based and airborne geophysical surveying of an Antarctic ice stream. Matt received his Bachelor of Arts and Master of Science degrees in Earth Sciences from Dartmouth College. After completing his PhD at Scripps Institution of Oceanography, Matt was a postdoctoral researcher at Scripps Institution of Oceanography and the Thompson Postdoctoral Fellow in the Department of Geophysics at Stanford University.
