Summary

My overall research and teaching interests are inter-disciplinary in nature, covering facets of geotechnical, environmental, transportation, geological, and chemical engineering. From a broad perspective, I am interested in the beneficial reuse of industrial byproducts in transportation systems (e.g., foundry sand in embankments and subgrade systems, cement kiln dust (CKD) and flyash for stabilization and strength improvements of weaker subsoil); remediation of metals-contaminated sites; use of geosynthetics in transportation corridors and environmental systems; imaging analyses; and the remediation of contaminated sediments in our nation's ports, harbors, and river systems. I developed these research interests as a consulting engineer for 10-plus years at two internationally prominent engineering firms.

As an engineering consultant, I worked on numerous geoenvironmental and geotechnical projects and developed an understanding on how to apply results from laboratory studies to successful field-scale applications. As an example, I coordinated a large laboratory investigation exploring the consolidation and strength properties of foundry waste mixes and used these results to conduct landfill stability sensitivity analyses, which ultimately allowed my foundry client to receive a major landfill expansion permit. Another example involved the development of an expert opinion on the chemical and physical characteristics of CKD on behalf of the cement industry in response to proposed new landfill disposal regulations from the Environmental Protection Agency. This "white paper" combined research results and field studies from across the nation and helped evaluate the merits of the proposed regulations. Planned research projects for the 2008/09 academic year include the following:

• Fate and transport of Cr(VI) in alluvial sediments and the vadose zone

• Weathering catalysts and retarders for chromium ore processing residue

• Long-term hydraulic evaluation of earthen cover systems

• Reconstruction of Railroads and Highways with In-Situ Reclamation of Materials

• Beneficial Reuse of Coal Combustion Byproduct Material to Stabilize Aluminum-Bearing Waste
