Plant community and restoration ecology
Plant – fungal interactions and species invasions
Grassland restoration, reconstruction, and management
My research program combines aspects of plant community and restoration ecology. I am broadly interested in how plant communities assemble and change through time and my research focuses on addressing this question though a variety of experimental approaches. Thus far, research in my laboratory has focused on studying temporal and spatial vegetation dynamics in deciduous forests and grasslands. This research involves using novel approaches to assess controls over and effects of species invasions from the perspective of the community and the invader. Current projects ask how initial plant pattern affects subsequent invasion in restored grasslands and how the presence of symbiotic fungi in grasses affects invasion and subsequent community structure and function. Findings from this research have advanced our understanding of grassland dynamics and shed light on how we might improve upon current grassland restoration practices. Members of my laboratory work with federal, state, and non-profit agencies to apply findings from these and additional studies to help inform grassland reconstruction and management practices in the Northern Great Plains.
