My research interests in marine science have focused on studies of the behavioral ecology of marine zooplankton, and how sensory perception mediates behavioral adaptations for locating food resources, avoiding predators and finding mates. Much of this research makes use of video microcinematography, high speed digital holography and automated video-computer methods for image and motion analysis. I am particularly interested in the role of photoreception in mediating potential predator-prey interactions within the plankton, including the role of bioluminescence in nocturnal predator-prey interactions, the role of vision in the feeding of larval fish on zooplankton and the role of sunlight in vertical migration of oceanic plankton to avoid visual predators. I am also interested in the role of planktonic grazers in harmful algal bloom dynamics; several ongoing studies are investigating the role of grazers in bloom dynamics of the toxic red tide dinoflagellate Karenia brevis with funding from the Gulf of Mexico.
