I am a PhD Candidate in the Ecology and Evolutionary Biology Program. I am interested in the effect of environmental gradients and land management on microbial community abundance and activity and, in turn, how changes in microbial communities feedback to influence nutrient cycling. My research focuses on the effect of alternative biomass cropping systems on carbon and nitrogen cycling, with specific focus on denitrification at the Landscape Biomass Project @ the Uthe Farm.
