- B.S.E., Geo-Engineering, Purdue University, 1988.
Current RolePrincipal Hydrogeologist.
CapabilitiesConceptual and numerical modeling of groundwater systems, three-dimensional scientific visualization of subsurface data and modeling results, and contaminant transport modeling. Expert user of MODFLOW, MT3D, GMS. Ecosystem services (ES) of perennial bioenergy crops, especially in marginal lands. Geospatial tool development for delineation of marginal land, determination of ES, and economic valuation of ES. Phytoremediation system design, assessment of remediation systems and natural attenuation, decision-making for long-term monitoring. Geostatistics and uncertainty assessment, including use of statistical/geostatistical methods in probabilistic estimation of radiologically contaminated soil volumes, modeling of complex aquifer-aquitard relationships, and assessment of flow model uncertainty. Water resources investigations, wellhead protection zone delineation, stormwater and flooding analyses, GIS. Environmental impacts of the energy-water nexus, especially for nuclear power plants, utility-scale solar energy, NORM, oil shale, and tar sands. Proposal writing and project management, including staff selection, progress and financial reporting, and quality assurance. State-licensed professional engineer.
- Principal investigator: Several projects focused on the ecosystem services of bioenergy crops in the Midwest. Development of probabilistic wellhead protection zones in glacial-drift and carbonate settings. Evaluations of flooding hazards at nuclear power plants. Formerly Used Sites Remedial Action Program (FUSRAP).
- Lead hydrogeologist and modeler: Argonne's phytoremediation site.
- Panelist: U.S. Government Accountability Office study of tritium leaks at nuclear power plants.
