The primary goal of my research program is to develop and refine estimates of the impacts of ongoing and future land use change and global change on agro-ecosystem processes and services. Projects are currently under development that will apply a combination of field-based measurements with agro-ecosystem models to assess:

  1. the water use and water use efficiency of sorghum, a potential bioenergy feedstock
  2. the impacts of perennial bioenergy feedstock production on sloping terrain
  3. the implications of introducing novel, highly productive lines of Switchgrass on agro-ecosystem services
  4. interactions of large-scale wind energy operations with surrounding agricultural fields
  5. the impacts of global change (increasing drought frequency, atmospheric CO2 and temperature) on the productivity and biogeochemistry of the corn-soybean agro-ecosystem.
