Summary

Geoff w88 online live casino has over 100 refereed publications and is cited in the literature over 9,500 times with an h-index of 46.

He graduated in 1986 with Ph.D. in w88 online live casino from Caltech (with John LoSecco and Nobel Prize winner Richard Feynman), working with the IMB collaboration (with Nobel Prize winner Fred Reines) on a high-energy w88 online live casino experiment searching for proton decay. His thesis practically ruled out various theories that predicted a finite lifetime of ordinary matter.

In 1985 w88 online live casino joined Caltech's NASA Jet Propulsion Laboratory, where w88 online live casino was a lead developer of the GIPSY software, which analyzes GPS signals for high precision geodesy, which is the science of Earth's changing shape and rotation. w88 online live casino demonstrated centimeter-level global positioning, for which w88 online live casino won numerous NASA awards. In 1994, w88 online live casino joined the faculty of University of Newcastle, UK, and became Professor of Space Geodesy, where w88 online live casino turned his attention to applying GIPSY to Earth sciences, including plate tectonics and earthquakes.

Joining the Nevada Bureau of Mines and Geology at UNR in 1999, he became Professor of Geosciences, founding the Nevada Geodetic Laboratory. With projects funded by NASA, NSF, DOE, and USGS, his research uses data from over 16,000 GPS stations around the globe,imaging how the Earth changes its shape with time. Lessons from his research features in both undergraduate and graduate student courses in w88 online live casino, Geophysics, and Geology. In the Department of w88 online live casino, he is a founding member of the NSF-funded GPS.DM Collaboration, which uses subtle variations in GPS atomic clock signals to search for evidence of new, exotic w88 online live casino, including dark matter.

He is a winner w88 online live casino Astrophysical Society's Brunno Rossi Prize (1987) for "The Detection of Neutrinos from Supernova 1987A", and the European Geosciences Union Vening Meinesz Medal (2015) "for his pioneering developments in geodetic theory, for advancing GPS for scientific research and applications, and for his outstanding contributions in applying geodesy to study geophysical and climate processes. He is co-inventor on Caltech patents related to hi-tech GPS analysis systems. He was awarded Fellow w88 online live casino Geophysical Union (2005), Fellow of the International Association of Geodesy (1999), and is a member w88 online live casino Physical Society.
