Research Interests
My laboratory studies marine bioacoustics with a focus on hearing and sound production in fishes and marine mammals. Laboratory studies utilize neurophysiological techniques to investigate the neural mechanisms of hearing and sound production. We also use SCUBA diving with underwater video to identify and study sounds produced by fishes during courtship and spawning. Recent work has focused on sound production by sciaenids (croakers and drums) in the estuaries of Florida. New research is aimed at studies on spawning aggregations of groupers. One major thrust over the next few years is the deployment of a large, sparse passive acoustic array on the West Florida Shelf to track the location of cetaceans relative to physical oceanography. We are also involved in studies of the hearing abilities of manatees and dolphins with both captive trained marine mammals, and wild and stranded cetaceans.
