My research focuses broadly on the roles of spatial and temporal heterogeneity in plant population and community dynamics with a strong focus on invasion dynamics and conservation. I split my time between applied projects and those testing general theories or hypotheses. My strategy for most of my research is to combine multifactorial experiments with mathematical models. Current work examines factors that affect the impacts of invasive species in the Polygonaceae (Polygonum and Rumex genera), invasive facilitation from nitrogen fixers, and invasive metacommunities.
