Research Interests
I focus on the Microbial Ecology of biogeochemical processes, particularly those that occur in the subsurface. Of particular interest are studies involving respiratory anaerobic microorganisms, such as those that reduce halogenated compounds and metals, in both natural and human impacted ecosystems. Recent projects have involved deep subsurface microbial activity in the Illinois Basin Mt. Simon formation; microbial community composition in the Mahomet aquifer (major drinking water source for Champaign); bioremediation of chlorinated solvents in low permeability zones; evaluation of sulfate reducing microbial growth in microfluidic devices; and detailed evaluation of the N-cycle in agricultural soils and tropical soils relative to greenhouse gas (nitrous oxide) formation.
