I am a plant community and evolutionary ecologist. I study how human actions affect the ecology and evolution of weedy and invasive plants, and the processes that generate and maintain biodiversity. To do this work I do a combination of field experiments, mathematics, and computational modeling.

My research allows me to advance fundamental theory while providing information needed to protect food security and to conserve biodiversity.
