Research Description

I am a plant ecologist broadly interested in the patterns, causes, and consequences of diversity with an emphasis on grassland ecosystems. My main research interests are directed towards understanding the influence of species interactions, especially plant-herbivore and plant-soil feedbacks, as well as biological invasions on the relationship between biodiversity and ecosystem functioning.
