Summary of research

My research combines molecular and traditional culture-based approaches to investigate microorganisms in natural habitats. My efforts are broadly directed toward the following investigations: (1) the role of bacteria in biogeochemical cycling in natural habitats - specifically related to nitrogen and sulfur cycling in high temperature / acidic environments, iron and manganese transformations in neutral pH environments, and nitrogen cycling in aquatic and terrestrial systems. (2) the diversity, physiology and genetic processes underlying microbial life in high temperature, low pH environments, (3) the assessment and quantification of microbial biodiversity within natural communities, especially pertaining to the effects of environmental and anthropogenic perturbations, and (4) the detection of microorganisms, their genes and associated activities in field and laboratory systems.
