Research Interests:

I am a microbial ecologist whose research focuses on understanding how microorganisms impact their environment and biogeochemical cycles and in turn, how an environment impacts microorganisms. I investigate both contaminated and pristine environments. My focus is primarily on bioremediation and natural attenuation in lakes, soils, and terrestrial sediments; the microbial ecology of pristine aquifers caves, pitcher plants, and salt marshes; and the microbial contributions to energy production.

Research Interests:

My research focuses on understanding the community of microbes in natural environemnts, as well as their impacts on the environment and biogeochemical cycles.  Major research interests include microbial community composition and bioremediation of aquatic systems, subsurface geomicrobiology, and microbial disease in natural environments.  My work also includes understanding the microbial ecology in contaminated enviroments, and its impacts on human health.

Research Interests:

I conduct microbial ecological research to study biotransformations of nutrients and contaminants, pathogen detection, and bioremediation.  On a molecular level I evaluated stress and toxicity levels and looked at protein level expression changes due to environment factors on human cells.
