The goal of my research program is to link empirical results and theory to develop and expand a framework for understanding the population and community dynamics of mutualism. My past and current research addresses this goal using a variety of natural systems, but focuses on ant-based mutualisms. Find out more about my research at mutalism.williams.edu.
