Mr. Horner began his career as an environmental well site geologist, providing geological characterization and technical oversight of well drilling and construction activities for characterization and compliance wells drilled at the U.S. DOE Hanford site. In 2008, after three years of field experience, Mr. Horner joined PNNL and began supporting the design and installation of various well networks required to deploy and monitor PNNL’s innovative environmental remediation technologies. Since joining PNNL, Mr. Horner has applied his expertise in site characterization and field operations to a variety of subsurface investigations, including geothermal resource evaluations, geological carbon sequestration, and compressed air energy storage (CAES). Mr. Horner is also active in the laboratory where his investigations have focused on the production of natural gas from hydrate bearing geologic media and the characterization of basalt samples reacted with supercritical CO2. Recently, Mr. Horner has expanded his construction oversite expertise to include various field deployment efforts in support of the Radiation Portal Monitor Program (RPMP), where he currently serves as the Field Operations Subtask Manager. His education includes a bachelor’s degree in Geology and a master’s degree in Geology, with an emphasis on seismic hazard analysis through paleoseismic trenching and investigations using tectonic geomorphology with various Quaternary age dating methods.
