My research explores the role of species interactions in driving the structure, function, and assembly of ecological communities, with emphasis on the dynamics of aquatic ecosystems. My work spans a diverse array of taxa (fishes, invertebrates, and salamanders) and my projects include both temperate and tropical ecosystems. My approach is integrative,  I use a combination of experiments, descriptive studies, and modeling to develop and test ecological theory and inform conservation and management.  I follow the scientific method but am aware that some of the most interesting phenomena in biology are inconspicuous and remain undiscovered; therefore I apply both a careful understanding of natural history and a willingness to conduct experiments when complexity obscures obvious pattern. My program currently includes four facets: 1) Population Dynamics,  2) Species Interactions, 3) Community Assembly and 4) Trophic Biogeography.
