Welcome to the Soil Biology and Ecology Lab

This web site provides a central hub of information on topics connected to soil biology and ecology in Michigan, the Great Lakes region and Uganda. Our research is centered on exploring the dynamic interactions between microbial communities and soil organic matter (SOM). Soil organic matter, the foundation of soil fertility, stores the largest fraction of terrestrial organic carbon (C), acts as a nutrient reservoir, and influences soil structure, water holding capacity, pH, and ion exchange capacity. Microbial communities mediate the formation and degradation of SOM, and thus control flows of carbon (C) and nutrients through soils and ecosystems. Because human induced environmental change can alter microbial genetic and functional diversity with impacts on SOM dynamics, it is vital we understand these interactions if we wish to sustain the critical ecosystem services SOM provides.
