| Geodesy and Tectonophysics Laboratory

GNSS site in the Natron Rift, Tanzania

GTL Vision: Our vision is to advance the theory of plate tectonics using geodesy and computational modeling while promoting inclusion, diversity, justice, equity, and accessibility in STEM education and research.

GTL Mission: The mission of GTL is to conduct research that entails measuring the Earth's surface motions with millimeter precision and using computational modeling to understand the physical processes driving the Earth's volcanoes, earthquakes, and continental deformation while training future leaders that are culturally effective to make both Virginia Tech and the world a safer and more inclusive place.
