Our research focuses on the discovery and interpretation of patterns of biodiversity at a variety of taxonomic and geographical scales. We use historical (phylogenetic) approaches to investigate questions that encompass the evolution of ontogeny, biogeography, function, behaviour, and population structure. A particular interest is the role that geography plays in the genesis and organization of genetic and taxonomic diversity. We use fishes as model organisms, with particular emphasis on tropical marine and freshwater species. However, our lab is also interested in the evolution of insects.
