Our agroecology research group focuses on understanding how plant-soil interactions mediate carbon and nitrogen cycling and placing this research within broader social and economic contexts. The necessity of sustainably producing food has never been more evident as agriculture both contributes to and is impacted by many global change issues. In particular, increased climate variability requires the development of resilient, regionally adapted production systems. Our research applies concepts from ecology and biogeochemistry to study nutrient cycling and organic matter dynamics within cropping systems from rhizosphere to global scales using on-farm, experiment station, greenhouse, and modeling experiments. Central topics of our research group include:

• Plant mediation of nitrogen mineralization through shifts in belowground carbon allocation

• Utilizing plant diversity to improve cropping system resilience

• Interdisciplinary collaborations to integrate agroecological knowledge into policy and management
