I am a plant ecologist studying biological invasions and their impacts on native plant communities and ecosystems. I research the impacts and interactions among co-occurring invasive plant species, and how these impacts might differ from invasions by single invasive plants. Because invasive species are an environmental concern, I design research that promotes scientifically sound invasive management policy and practice. Broadly, my research program seeks to address the complex issue of nonnative, invasive species through two avenues:
understanding the ecological functioning of invaded ecosystems and predicting which nonnative, invasive species are likely to have the largest environmental impact; and
promoting better policy for curbing nonnative species introductions through assessing efficacy of policies and understanding socio-cultural aspects of invasions.
