Our lab is primarily interested in the integration of sensory biology and behavior with functional morphology. We employ behavioral assays, field observations, and comparative morphology to test hypotheses about the evolution of biological structures. We have concentrated primarily on the elasmobranch fishes, which provide an opportunity to investigate various sensory modalities among closely related but morphologically dissimilar species. We also maintain an active research program studying the annual blacktip shark migration. This work incorporates aerial surveys, transmitter instrumentation, and field observations.
