Molecular microbial ecology, molecular genetics, and environmental microbiology. Ongoing research projects include: Community-level analyses linking bacterial community structure, function, activity and diversity in metal-contaminated and pristine river sediment systems; exploring the role of the microbial community in the success of invasive weeds; examining the role of charcoal from forest fires in controlling the distribution and activity of nitrifying bacteria in forest soils; fate and transport of microbes in the environment; microbial ecology of the gastrointestinal tract; using the soil bacterial community as an early warning system for elevated CO2.
