Research Interests

My research examines interactions between plants and animals, focusing on the dynamics that arise when traits that defend plants against antagonists alter relationships with mutualists.  I am interested in how these dynamics structure interactions at different ecological scales, from pairwise relationships up to whole-community responses, as well as how tradeoffs in traits that drive attraction and defense affect fitness in plants and the animals they host.  Specifically, my research examines how the composition of floral rewards and flowering plant communities affect plant-pollinator interactions and pollination.  Using a combination of field experiments and surveys, as well as lab studies, I examine the consequences of variation in floral rewards for native pollinators and plant-pollinator communities in natural and agriculture ecosystems. I use bumble bees as a model lab system to examine pollinator behavior, physiology and health, while my fieldwork addresses interactions between pollinators and individual plants, plant populations, and whole plant communities.
