Research interest

Microorganisms are key players in various biogeochemical cycles and can serve as bio-indicators of ecosystem function and environmental health. My primary areas of research focus on understanding the relationship between structure and function of microbial communities. I have studied various terrestrial and marine ecosystems in order to better understand how community structures, in terms of abundance and diversity, correlate to their activities and processes. These include microbial pathways in the biogeochemical nitrogen (N) cycle, metal transformation, biodegradation, and primary production. I have employed a variety of analytical, microbial, molecular and stable isotope techniques to identify and quantify the functional members of microbial communities of interest. My current research emphasis is on microbial communities responsible for N2O and N2 production in terrestrial and marine ecosystems.
