Macro-scale invasion dynamics
Species invasions are an urgent threat to global biodiversity, but also present unique opportunities for testing general ecological concepts. With an emphasis on freshwater fishes, we use a combination experiments, observational studies, and modeling to better elucidate the fundamental drivers of biological invasions.
We are working closely with collaborators from Louisiana State University and the University of North Carolina at Wilmington to develop cutting-edge new research that will fundamentally change the way we model and manage species invasions.

Positive biotic interactions in freshwater ecosystems
Throughout the last century, ecologists have learned a great deal about how negative biotic interactions (competition, predation, and parasitism) operate in nature. However, research on positive interactions such as mutualism, commensalism, and facilitation is still developing. We use symbiotic reproductive interactions among stream fishes as a model system for understanding how positive interactions function in nature.
