Optimized Lab Protocols for Testing Soils
Research
- Ecosystem Ecology
- Plant-Microbe-Soil Interactions
- Coupled Biogeochemical Cycling
My research goals are to improve our predictive understanding of how the physical environment alters the structure and function of ecosystems, either natural or anthropogenic. Most of my research involves investigating how soil microbes mediating the cycling of carbon, nitrogen, and phosphorus and its impact on tree productivity based on mycorrhizal associations. One decade-long project involves understanding the role of elevated soil pH and/or phosphorus influencing soil microbial functional capacity and forest carbon sequestration. My research draws from soil science, ecosystem ecology, microbial ecology, and forestry.
