Professional Experience
Research Geophysicist - US Geological Survey, Water Resources Division, Sacramento, California. June 2002-present. Duties include establishing the USGS Western Remote Sensing and Visualization Center as a cross-discipline facility designed to foster new collaborative research project among the USGS divisions through evaluating and adapting new technologies. My research group is: 1) using interferometric synthetic aperture radar [InSAR] and Global Positioning System [GPS] measurements to characterize and model the 3-dimensional deformation field associated with Aquifer Storage and Recovery programs and overdrafted aquifers; 2) mapping the spatial extent of ground-water barriers with InSAR; 3) evaluating if InSAR can be used to identify subsidence precursors to mine shaft/tunnel collapse; 4) recognizing and removing anthropogenic deformation in tectonic GPS networks; 5) imaging debris flows with tripod-mounted Lidar to help mitigate the hazards following the 2003 southern California wildfires and the 2004 Carson City Fire, Nevada; 6) evaluating tripod-mounted Lidar for collecting indirect flood measurements and habitat change; and 7) using tripod-mounted Lidar and multi- and hyper-spectral imagery to track vegetation changes following the 2003 southern California wildfires.
NASA Post-Doctoral Fellow - U.S. Geological Survey, Earthquake Hazards Team, Menlo Park, California. 1998-2002. Duties included the analysis of InSAR and GPS observations to assess the magnitude and spatial extent of human induced deformation, such as water, oil and gas pumping and recharge, on the SCIGN GPS network in Los Angeles, CA. I also developed and surveyed two large GPS arrays (60-100 site) across the Basin and Range that spanned California, Nevada, Oregon, and Utah.
