Research Interests:
My research area is plant ecology, with emphasis on restoration ecology, soil ecology, and invasive species ecology. I work primarily in California shrublands, grasslands, and deserts, including sites impacted by anthropogenic nitrogen deposition, urbanization, grazing, agriculture, invasive species and frequent fire.  Members of my lab currently study impacts of invasive species and nitrogen deposition on plant-soil feedbacks, biodiversity decline, productivity, competitive hierarchies and functional traits of native and exotic species, vegetation type conversion, diversity and functioning of mycorrhizal fungi, nutrient dynamics, and restoration of impacted ecosystems.
