My research concerns the origin and maintenance of biological diversity: where do species come from, what directs the evolutionary course they take, and what ongoing ecological processes affect them today? To study such questions, my laboratory integrates approaches from systematics, ecology, behavior, genetics and functional morphology, taking both observational and experimental approaches in the field and in the laboratory. In many respects, lizards are ideal organisms for such synthetic studies.
