My research broadly addresses the ecology of plants and the application of science to improve invasive species management and restoration success. I investigate the impacts of introduced invasive plants on native plant populations, communities, and ecosystem processes. My current work examines the abiotic and biotic mechanisms by which a widespread invasive shrub, Scotch broom (Cytisus scoparius), limits reforestation success. Specifically, I test the hypothesis that changes in nutrient availability, allelopathy, and the disruption of the mycorrhizal mutualism that result from Scotch broom invasion, remain as soil legacies that ultimately hinder Douglas-fir establishment. A major component of my research examines the temporal dynamics of these invasive species impacts and I am currently investigating both the development of soil legacies over time following invasion as well as their persistence with time following invader removal. My research is funded by a grant from the National Science Foundation.

I am interested in species distributions, community assembly, and functional traits, especially in stringent environments. I am currently researching grasses in the Colombian tropical alpine, with a focus on the genus Cortaderia. Since 2011, I have also been studying the invasive grass, Ehrharta erecta, focusing on species impacts and management methods.

I study the effects of anthropogenic change on annual plant demography and community composition in California’s Mojave Desert, currently undergoing a renewable energy boom. This region is home to many rare and special-status species – how can we detect these species, avoid impacting them, and mitigate impacts when they can’t be avoided? I combine observational and experimental approaches to gain insight into desert annual performance in natural and human-modified landscapes. Desert annuals exhibit strong response to microsite heterogeneity and moisture availability; can the response of plants to these sources of natural variation help us predict demographic response in human-modified landscapes? I use matrix models to compare performance of closely related rare and common annuals (Eriophyllum mohavense and Eriophyllum wallacei) in different microsites and in an experimental shade treatment mimicking the effects of a photovoltaic array.
