My students and I address a broad range of issues in ecology, especially evolutionary ecology, in an effort to understand the structure and dynamics of ecological populations and communities, life histories, and underlying behavioral mechanisms.  The students conduct mainly empirical studies in a diverse array of systems and organisms (see below) and often collaborate with me in developing related models.  Most of my own work is theoretical, with recent focus on game theory, sex ratios, disease models, and metapopulations.  Students interested in gaining experience with a mix of empirical and modeling work are especially encouraged to apply for graduate study.  Highly motivated undergraduate researchers are also welcomed into the lab, often collaborating with one or more of the graduate students.  Though some of us and some of our individual projects may exclusively use theoretical or empirical approaches, a goal of the group is to help tighten connections between theoretical and empirical work in ecology.
