Research Interests

My research is focused on quantification of the biological and physical dynamics of the soil biome and its relationship with climate and water availability. I use lab and field trials to understand and assess the soil ecosystem and its members and functions and develop models of the soil biosphere that consider their important impacts on root growth, plant nutrient use efficiency, carbon budgets, water, and that consider an important subset of the soil microbiome. Additionally, my research aims at understanding the impacts of various types of common Soil Organic Matter (SOM) amendments - including manure, cover crop biomass, and other residues (e.g. biochar) that will be used in conjunction with local soils to evaluate availability of soil-N and -P using data from collaborative field and controlled environment experiments. My other research goals include developing a mechanistic understanding of greenhouse gas emissions, including nitrous oxide and methane emissions - and the role of the biotic components and understanding the impact of temperature, CO₂, water and soil management on nitrous oxide and methane emissions. Finally, I look at G x E x M relationships to understand how to use the models effectively to sustainably manage these systems.
