Senior Technical Advisor with over 40 years of experience conducting environmental assessment and remediation projects. Extensive knowledge and expertise in environmental characterization and remediation as it relates to the Department of Energy’s (DOE) Hanford Site. Since joining PNNL in 2016 he Advises PNNL program and project managers in areas of research involving disciplines such as geology, hydrology, geochemistry, microbiology, computational modeling, and environmental engineering as it relates to systems-based characterization, monitoring, and remediation. Particular emphasis is on deep vadose zone and groundwater remediation strategies and computer modeling and analysis. Provides guidance in developing and demonstrating systems-based approaches for environmental characterization, monitoring, and remediation. Consults on laboratory testing and analysis to develop and optimize innovative hydrogeological and biogeochemical approaches based on fundamental understanding of controlling processes for application in soils, surface water, and groundwater environments. Provides leadership to, collaboration with, and mentoring of multi-disciplinary teams of scientists and engineers including experimental design and execution, computer simulation, and scale-up from laboratory results to field applications.
