Research Interests:

Throughout my career, my research has focused on the geochemical cycling and chemical speciation of metals in natural aqueous environments. This has taken me from research cruises in the Atlantic and Indian Oceans and the Black Sea to “mucking in the mud” in wetlands.

My most recent research project involves a study of seasonal changes in redox conditions and metal fractionation in freshwater wetlands bordering Saginaw Bay, MI. At CCU, we are continuing the analysis of Saginaw Bay sediments, as well as constructing voltammetric microelectrodes for studies in local saltmarsh sediments. We will also be working with Integrated Environmental Technologies, located in Little River, SC, to explore the application of their “EcaFlo” technology for the treatment of stormwater and wastewater.

Current Funding:

Michigan Sea Grant Program, "An Evaluation of Seasonal and Temporal Variability in Potential Trace Metal Remobilization in Coastal Wetlands Sediments Using Voltammetric Microelectrode Technology and Solid-Phase Extraction Techniques", 3/2003–2/2006, $63,164.

 


Professional Societies:
