Research Interests

Our research group's primary interests are in the ecology and epidemiology of parasites and pathogens of marine organisms and marine aquaculture.

Our currently funded epidemiological research is on parasites and pathogens of penaeid shrimp [White Spot Syndrome Virus, Taura Syndrome Virus, & Necrotizing Hepatopancreatitis bacterium] and blue crabs (Callinectes spp.) [White Spot Syndrome Virus & Hematodinium spp. - a dinoflagellate]. Our goal is to understand the processes and factors that cause epidemics and maintain populations of these parasites and the consequences that the parasites have for their host populations. Our approach combines field and laboratory work with theory and numerical, statistical, and simulation analyses.

Our funded marine aquaculture research is on shrimp (primarily Litopenaeus vannamei) and spotted seatrout (Cynoscion nebulosus). Our goals are to develop and refine low-water-use, low-discharge technology to support the development of a U.S. marine shrimp culture industry and for stock enhancement research of spotted seatrout.
