Research Experience

Staff Scientist, Argonne National Laboratory 2001-present.

Postdoctoral Research Associate, Argonne National Laboratory 2000-2001.

My current research program is focused on biogeochemical processes affecting the transformation of organic and inorganic contaminants. Specific projects include: 1) Reduction of U^VI by biogenic Fe^II-bearing minerals formed from microbial dissimilatory iron reduction; 2) reduction of organic and inorganic contaminants by microbially reduced humic substances; 3) effects of transition metals on the reductive dehalogenation of chlorinated aliphatic hydrocarbons by mixed Fe^II/Fe^III hydroxides ("green rusts"); 4) reduction of trace elements (e.g., U^VI, Hg^II, Cu^II, etc) by green rusts; 5) interaction of trace elements with microbial exopolysaccharides, bacteria, and iron oxyhydroxides; and 6) X-ray microprobe imaging of microbe-metal interactions.

National Research Council Postdoctoral Fellow, Tyndall Air Force Base 1997-2000.

I examined processes affecting the fate and transport of chlorinated hydrocarbons in subsurface environments. Specific projects included: 1) Reductive dehalogenation of chlorinated aliphatic hydrocarbons by green rusts; 2) investigation of the potential for humic-transition metal complexes to act as electron transport mediators in the reductive transformation of organic contaminants; and 3) design, construction and field-testing of flux chambers to measure TCE volatilization from TCE-contaminated aquifers.

Graduate Research Assistant, Ohio State University 1987-1997.

I participated in many interdisciplinary research projects in the areas of environmental microbiology and environmental chemistry including: 1) Riboflavin overproduction by Micrococcus luteus during pyridine degradation; 2) isolation and characterization of aromatic N-heterocycle-degrading bacteria; 3) biodegradation of aromatic N-heterocycles in subsurface sediments; 4) sorption of aromatic N-heterocycles to clay minerals; 5) effects of sorption on the biodegradation of aromatic N-heterocycles; 6) sorption of atrazine and alachlor to subsurface sediments; 7) isolation and characterization of humic substances in lacustrine sediment porewaters; and 8) association of organometallic compounds with aquatic humic substances.
