Research Program Summary
My research goals are to improve our understanding of how the physical environment alters the structure and function of ecosystems, either natural or anthropogenic. Most of my research involves investigating the influence of soil microorganisms mediating the cycling of carbon, nitrogen, and phosphorus. One active project involves understanding the role of soil acidity and phosphorus influencing the carbon and nitrogen cycle in acidic hardwood forests. My research draws from soil science, ecosystem ecology, microbial ecology, and forestry.
