I am interested in how environmental variation, on multiple scales, affects the diversity and function of ecological communities. For my dissertation I studied how regional habitat loss can alter the architecture of local plant-pollinator interaction networks. As a postdoc in the Gratton lab I lead a team researching native pollinators in bioenergy grasslands. We are working to understand how local management (harvesting) and variation in the surrounding landscape combine to affect pollinator diversity and function.
