Biographical Sketch: Greg Anderson
Dr. Anderson is a Mendenhall Postdoctoral Fellow at the US Geological Survey in Pasadena. He received his Ph.D. in Earth Sciences from the University of California, San Diego (UCSD) in 1999, where he specialized in GPS and tiltmeter studies of crustal deformation and statistical studies of earthquake stress transfer. As a graduate student and postdoctoral researcher at UCSD, he led several field GPS surveys in southern California, including co-coordinating several large surveys following the 1999 Hector Mine earthquake, and was part of a team that designed a novel long-baseline tiltmeter for submarine volcano deformation monitoring. Since coming to the USGS in December 2001, he has developed software for rapid estimation of strain fields from SCIGN data, has studied crustal deformation in the Salton Trough from survey-mode GPS and trilateration, and is developing techniques for estimation of earthquake probabilities from geodetic data.
