Jay Clausen is a Physical Research Scientist with the US Army Corps of Engineers, Engineer Research and Development Center, Cold Regions Research and Engineering Laboratory (CRREL) in Hanover, New Hampshire. Since 2005, Jay has conducted research on the application of the Incremental Sampling Methodology (ISM) to military ranges containing energetics and metals in particulate form; the fate-and-transport of lead, tungsten, and energetics; assessment of range residues; application of wide area assessment (WAA) sensors for studying ranges; and the use of laser-induced breakdown spectroscopy (LIBS) for a variety of applications. Prior to joining CRREL, Jay worked for 14 years in the environmental consulting field for AMEC as a Senior Hydrogeologist/Project Manager and Lockheed Martin focused on Department of Defense and Department of Energy issues related to chlorinated solvents (TCE) and radionuclide characterization and cleanup. Jay earned a bachelor’s degree in geology from the University of Nebraska at Omaha and a master’s degree in the geosciences from the University of Maine with a focus on hydrogeology and geochemistry. Jay is currently working on an PhD in the Natural Resources and Earth System Science program at the University of New Hampshire focused on the application of ISM techniques to soils containing metallic residues. Jay is a certified professional geologist in the states of Kentucky, New Hampshire, Texas, and Washington and a certified professional hydrogeologist in the state of Washington.
