Description:
To understand the molecular interactions between an invertebrate host and its parasite or bacterial pathogen (the eastern oyster Crassostrea virginica and its parasite Perkinsus marinus and the blue crab Callinectes sapidus and strains of Vibrio parahaemolyticus) and their role against disease. To develop molecular tools that will allow us to determine the presence of cryptic infections in oyster seed stock and overwintering populations and pathogenic vibrios in blue crabs. To identify molecular markers that may help to determine which individual oysters or strains may exhibit increased resistance to the parasite for selective breeding.

Developing a habitat model for mysids, an important link in Chesapeake Bay food webs
Mysids are important mesozooplankton prey for many species of fish in Chesapeake Bay and are an important link in transferring energy from lower to upper trophic levels. Mysids also serve as biological vectors for benthic-pelagic coupling due to their diel vertical migration and omnivorous prey-switching behavior, which makes mysids important regulators of food web architecture. Despite their central role in coastal food webs, surprisingly little is known about mysid ecology and dynamics in Chesapeake Bay.
