Current Projects
- Evaluation of the health and reproductive status of older, post-market
size Crassostrea virginica as a key to Perkinsus marinus
resistance in natural populations. With E.M. Burreson, funded by the Sea
Grant Oyster Disease Research Program.
- Native oyster restoration in Chesapeake Bay. With E.M. Burreson and
others, funded by the NOAA Chesapeake Bay Office.
- Crassostrea ariakensis-pathogenic Bonamia: The source of Bonamia,
the role of Crassostrea virginica in epizootics, and the pre-patent
period. With C. Audemard and E.M. Burreson, funded by the NOAA Chesapeake
Bay Office.
