J. Ramon Arrowsmith
ramon.arrowsmith (at) asu.edu
Ramon Arrowsmith is a Professor of Geology at Arizona State University, and conducts research in active tectonics, quantitative structural geology and geomorphology. These include paleoseismology, earthquake geology, theoretical studies of faulting and hillslope development, and Quaternary Geology and desert surface processes. Active areas of geographic concentration include the San Andreas Fault system, Arizona, central Asia, Xinjiang China, Baja California, and the Afar region of Ethiopia (for the geologic context of paleoanthropologic studies). He was an original PI on the GEON project and pushed early prototype development of the GEON Lidar Workflow, the predecessor to OpenTopography.

Chris Crosby manages day-to-day operations of the OpenTopography Facility. Trained as a geologist, he has worked on paleoseismology, earthquake geology, and active tectonics research in the western US, Caribbean, and Central Asia. He is interested in utilization of cyberinfrastructure to manage and improve access to earth science data and processing tools. Chris is an expert in the management, distribution, processing, and application of high-resolution topography acquired via lidar (Light Detection and Ranging) technology and has guided the development of OpenTopography since its inception. In addition to his work on OpenTopography, Chris also manages Geodetic Imaging (Terrestrial Laser Scanning (TLS), photogrammetry, and Synthetic Aperture Radar (SAR)) at UNAVCO in Boulder, CO.

Chelsea Scott is a postdoctoral scholar at Arizona State University. She conducts research in active tectonics, geophysics, and structural geology with study areas in the western US, Japan and South America. She is particularly interested in developing topographic differencing techniques to image near-fault surface deformation. Scott earned her PhD from Cornell University where her doctoral research focused on using Synthetic Aperture Radar (SAR) imagery to constrain coseismic surface deformation.
