My research primarily focuses on understanding change in plant communities due to anthropogenic actions and natural forces, viewed chiefly through the lenses of ecology and evolution. In particular, I have studied vegetation change in estuarine wetland and upland communities, unintentional selection on restoration plant materials, the mechanisms driving invasive plant dominance and the effects of these plants on the communities they invade, and plant-soil feedbacks. I address these subjects using field, greenhouse and lab experiments, including vegetation surveys, seed bank assays, and in vitro and molecular analyses. I have worked in a wide range of habitats, including Great Lakes estuaries, oilfields and badlands of the northern Great Plains, hot deserts of the southwest, and forests of New England.
