High temperature process research is the cornerstone of my research program. Current and recent projects involve synthesis of carbide ceramics, vapor transport of rare earth element halogens, and the enhancement of copper and silver extraction from flotation concentrate. Other recent research focused on the study of fundamental properties of ionic melts such as slags and molten salts.
Energy and related environmental considerations provide impetus for much of my research. My approach has been to develop ways to recover recyclable commodities and/or energy in addition to destroying or stabilizing hazardous waste components. Examples include thermal processes that recover gas or liquid fuels from municipal solid waste, automobile shredder residue, tires, and various polymer wastes. I also investigate methods for recovering metal from electronic scrap, spent catalyst, geothermal brine, organometallic, and other forms of industrial waste.
I also have an active research interest in aqueous processing applications, including hydrometallurgy, corrosion, and wastewater treatment. One of my current projects relates to the development of a novel continuous flow ion exchange system for capturing metal ions from very dilute wastewater sources such as acid rock drainage.
