Environmental Geochemistry and Geomicrobiology Laboratory

Jeremy B. Fein


Water-rock interactions control mass transport in virtually all near-surface geologic systems. The research conducted in my laboratory isolates and studies reactions that control the fate and transport of heavy metals and radionuclides in groundwater and surface water environments.  The results of the research can be used to construct quantitative models of the effects of bacteria on mass transfer in water-rock systems, improving our ability to understand contaminant transport in the environment and to design effective remediation approaches. Students who conduct research in my group obtain a firm grounding in chemical thermodynamics and kinetics, and they gain considerable expertise in experimental aqueous geochemistry, geomicrobiology techniques, and a wide range of analytical approaches. My previous students have been highly successful in obtaining research positions either as postdoctoral researchers, university professors, or in the environmental industry.

Problems we are working on

The overarching goals of the research being conducted in my group can be summarized under four major categories:

1) Measuring and modeling the effects of bacteria and other microbes on the speciation, fate, and bioavailability of heavy metals in the subsurface.

2) Determining the environmental behavior of engineered nano-particles in water-rock systems.

3) Quantifying the thermodynamic stabilities and solubilities of uranyl peroxide nanoclusters in aqueous systems.

4) Testing the ability of ionic liquids to extract bitumen from geologic matrices in order to design environmentally-friendly methods of harvesting oil shales and tar sands.
