Current Projects

Biomass feedstock is a major consideration in second-generation (cellulosic) biofuel development. While there is hope that systems based on polycultures and perennial species may emit less N2O than conventional agricultural crops, this reduction may be contingent on previous land use and conversion methodology, phase and length of establishment, soil type, and management of inputs and production processes. My research aims to provide direct comparisons of N2O fluxes between potential bioenergy feedstock systems and evaluate the relationship between daily N2O flux and environmental factors.

Research and Professional Interests

To provide a scientific basis from which farmers can inform decisions about how best to manage rural landscapes under the mounting pressure to simultaneously produce, maintain, and develop ecosystem services such as air, soil and water quality, biodiversity and aesthetics, and contribute to the basic science of agronomy and ecology by generating knowledge about management effects on agro-ecosystems that will assist the public, agencies, and policymakers.
