Current research focuses on improving our understanding of the linkages between microbial community and diversity, and microbially mediated processes providing ecosystem services related to metabolic functioning, in agronomic and environmental systems. In our research, we integrate multiple technologies to discern any connections among diverse microbial communities, their metabolic functions and the land systems they reside. The technologies include but are not limited to, Transmission electron microscopy (TEM), X-ray diffraction spectroscopy (XRD), molecular biology, Metagenomic, and bioinformatics tools. These tools provide the ability to elucidate microbial patterns of community structure and distribution involving their contributions to nutrient cycling and the transformations of pollutants in soils, sediments and water.
