Overview
My research focuses on understanding how ecosystems function, with a focus on feedbacks between plants and soil microbial community structure and function and how disturbance, land-use, and environmental change alter this relationship and fluxes of water, carbon, and nutrients across forested and wetland landscapes. I have worked in numerous ecosystems spanning natural forested wetlands to northern hardwood forests to intensively managed pine plantations. I have also worked in bioenergy intercropping systems and on studies investigating the amelioration of degraded agricultural soils.
