Geoff Blewitt
Professor, University of Nevada, Reno
My major area of interest is geodesy, ranging from geodetic theory, technique, data analysis, and software development on the application of space geodesy to solid Earth science and fundamental physics. I have a Ph.D. in Physics from Caltech, and I am an AGU Fellow. My papers have been cited over 17,000 times, with an h-index of 60. I have served as President of the AGU Geodesy Section.
