Research Interests

My research interests lie at the interface of microbial ecology and environmental engineering. At this interface, molecular techniques are utilized as powerful tools for the analysis of microbial populations in engineered and natural treatment systems, allowing us to move away from the "black box" paradigm common in biological waste treatment. Environmental process engineering is approached from a fundamental standpoint- combining the insights from molecular approaches with innovative process experiments and modeling. This combined engineering/molecular/ecological approach is being used to assess issues in biological treatment such as: (1) growth, life strategies, and interactions of key microbial populations in treatment systems, (2) development of novel reactor designs and the coupling of reactor performance to microbial community structure, and (3) integration of results from molecular assays with treatment process modeling.

Current research projects include analysis of the microbial processes in industrial and domestic wastewater treatment systems, landfills, and groundwater remediation sites.
