Environment and Natural ResourcesFaculty Professor, School of Environment and Natural ResourcesMy research interests are focused on soil microbial ecology and the role of management in affecting the functioning of soils within ecosystems. The common research approach is biochemical properties and processes in combination with microbial community analysis. The research has focused on the effects of physical disturbance and organic C inputs on soil ecology of soil communities. Methodologies that have been used extensively are enzyme activities, microbial biomass, direct counts and functional diversity (BIOLOG). Profiling of microbial communities methods include phospholipid (PLFA) and PCR based nucleic acid analysis. My lab is doing in-depth studies using stable isotopic probing techniques for tracking 13C into PLFA biomarkers during decomposition and methane cycling in soils.
