We utilize ecological, molecular genetic, and numerical techniques in field and greenhouse studies to address questions in ecology and evolutionary biology.  Our research interests include evaluation of hybridization as an evolutionary stimulus, the evolutionary dynamics of invasion, the ecology and evolution of mutualisms, and landscape genetics of upland prairie species in the context of range responses to climate change.  We are currently focused on the invasive false brome (Brachypodium sylvaticum) as a model system for investigating fundamental questions in ecology and evolution.
