Areas of Research Specialization: Invertebrate Zoology, Marine Biology, Animal Nutrition, Physiological Ecology, Behavioral Ecology My investigations have explored the functional aspects of invertebrate zoology. Most of these studies have focused upon physiological, behavioral, and ecological aspects of nutrition of echinoderms. Recent studies have emphasized impacts of anthropogenic disturbances, particularly elevated sea surface temperatures, ocean acidification, and microplastic pollutants. This work upon novel challenges to sea animals has led to increased involvement in environmental policy and conservation efforts.
Research Group Focus
Many of our studies have focused upon physiological, behavioral, and ecological aspects of nutrition of echinoderms. The herbivorous sea urchins Lytechinus variegatus, Echinometra lucunter, and Strongylocentrotus droebachiensis have been the subject of many of our investigations, but we have also studied the more carnivorous sea urchin, Eucidaris tribuloides, as well as carnivorous and omnivorous starfish and detritivorous sea cucumbers. This research has highlighted many differences between herbivore, carnivore, and detritivore strategies of feeding and digestion.
In future studies we will continue our investigations of invertebrate nutrition and feeding behavior, particularly as this interfaces with physiological and population ecology. We have been integrating our research efforts with agencies involved in echinoderm fisheries. Growth in these fisheries has out-paced our understanding of echinoderms and the communities in which they reside. Special attention currently is being devoted to the describing the impacts of elevated sea surface temperatures and acidities upon the functional well-being of echinoderms and other marine invertebrates. We have also begun to investigate the impacts of microplastic particles upon aquatic invertebrate communities.
