I have very broad research interests that span the subdisciplines of physiological ecology, community ecology, and macroecology and evolution. In general, I am interested in how physical constraints on the survival, growth and reproduction of individuals influence the ecology and evolution of communities and ecosystems. Most recently, I have been working to develop what my collaborators and I refer to as the metabolic theory of ecology. This theory deals explicitly with the effects of body size, temperature and stoichiometry on ecological and evolutionary rate processes. In the coming years, I hope to further develop these ideas using a combination of theoretical, experimental and field approaches.
