By collecting and analyzing Global Positioning System (GPS) data from stations around the world and satellites in space, Geoff Blewitt, professor of geosciences in the University of Nevada, Reno's Nevada Bureau of Mines and Geology, is able to study changes in the Earth's crust with great precision. The result is a series of significant discoveries, any one of which has changed scientific understanding and offers implications for the way we live and think. Considered together, they mark an impressive career and body of research.
