Current Research

Restoration is a method of biological conservation in urban areas where ecosystems are subject to a suite of natural and anthropogenic disturbances. Restoration can also serve as an experimental method to investigate ecological processes. By attempting to reassemble components of an ecosystem, we learn how organisms interact with other organisms, their environment and human activities. In practice, restoration often seeks to restore the entire ecosystem, including not only native organisms, but also ecological processes and biotic interactions for long term sustainability. However, little is known about how the practice of restoration, typically an aboveground activity, influences key ecosystem processes that often occur belowground. My research investigates the impacts of biological invasion and restoration on above and belowground interactions. This work will contribute to basic ecological knowledge about the temperate woodlands, globally rare tallgrass prairie ecosystems, and the processes and interactions between plant and soil communities that determine biological diversity in the Midwest.
