I study how microorganisms influence the prevailing chemical conditions of a variety of “natural” and man-made systems. I am particularly interested in how the ecology, physiology, and in-situ activity of these microorganisms influence the fate of environmental contaminants. I am also interested in how microbial communities respond (in terms of community structure and activity) to physicochemical changes in their environment.
The work in my lab currently focuses on microbially mediated redox transformations of iron and sulfur species in acid mine drainage (AMD)-impacted systems, microbially-influenced corrosion, and microbial processes associated with flue gas “scrubbers” at coal-fired electric power plants.
