Short Research Description

My students and I study the microbial ecology of both natural and engineered systems. We use molecular tools to investigate microbial community structure and function in lakes and activated sludge. We are particularly interested in phosphorus, nitrogen, and carbon cycling in lakes and how this relates to eutrophication and water quality. We are using highly resolved time series sampling of multiple lakes, combined with metagenomics and meta-trascriptomics to explore how different lineages of freshwater bacteria contribute to this cycling. We are also engaged in metagenomic and post-genomic approaches to dissecting the metabolism of bacteria specialized in the sequestration of phosphorus in activated sludge. This information will ultimately lead to the construction of more predictive mechanistic and ecosystem-scale models to describe such processes as wastewater treatment and freshwater nutrient cycling
