D. Sarah Stamps

Assistant Professor

D. Sarah Stamps is a geophysicist that measures millimeter precision surface motions with GNSS/GPS and employs computational modeling to investigate the physics driving those motions. She is also an active member of the NSF EarthCube Science Committee and the NSF UNAVCO Education and Community Engagement Committee intent on helping to modernize geosciences for our cyber-connected society and advancing geoscience technical expertise in developing countries.


Ph.D., Geophysics/Geodesy, Purdue University, 2013

B.Sc., Earth Sciences and Mathematics minor, The University of Memphis, 2007

Our work entails measuring the Earth's surface motions with millimeter precision and using computational modeling to understand the physical processes driving Earth's volcanoes, earthquakes, and non-seismic deformation. We tackle questions such as: How and why does the Earth move and deform? Why do continents break apart? How do volcanoes influence continental rift initiation?

In the Geodesy and Tectonophysics Laboratory at the Virginia Tech Department of Geosciences we explore topics in lithospheric dynamics, mantle-lithosphere interactions, and active tectonics by (1) collecting and analyzing high precision Global Navigation Satellite System (GNSS) observations and (2) testing hypotheses with kinematic and geodynamic computational modeling.
