Research Interests

My research focuses on nutrition and host/parasite interactions in shellfish and fish. I am especially interested in the effects of environmental factors including pollution on host/parasite interactions, and immunological, biochemical and pathological responses associated with exposure to diseases and anthropogenic chemicals. In the nutrition aspect, I am especially interested in essential nutrient “upgrading” and transfer, trophic interactions and food webs and biochemical processes affecting fishery production in marine coastal environments. I am also interested in conducting research to understand the effects essential nutrients and growth factors in enhancing shellfish/fish growth and survival, and the effects of environmental stress on development and reproduction of aquatic organisms.

Recently Completed Projects

1. Evaluation of toxicity of Deep Water Horizon Oil spill and dispersants on the physiological and ecological responses of the commercially and ecologically important eastern oyster Crassostrea virginica (Stratus Consulting Inc.).

2. Fatty acid and sterol metabolism in planktonic heterotrophic protists: essential nutrient upgrading and transfer and their ecological implications in pelagic food webs (National Science Foundation, USA)

3. Effects of plankton composition and nutritional quality on growth of newly metamorphosed winter flounder (Collaborative Marine Education and Research Program, NOAA, USA).

4. Enhanced tautog (Tautoga onitis) survival via essential fatty acid enrichment of larval feed (Collaborative Marine Education and Research Program, NOAA, USA).

5. Lipid metabolism in the oyster protozoan parasite, Perkinsus marinus, and the role of host lipids in the development and proliferation of the parasite (National Science Foundation, USA).

6. Development of a chemotherapeutic protocol for eliminating and/or reducing perkinsus marinus from infected oysters (ODRP, Sea Grant, NOAA, USA)

7. Evaluation of inherent and induced thermal-tolerance in protection of oyster populations from summer mortality caused by Dermo and MSX parasitism and thermal stress (ODRP, Sea Grant, NOAA, USA).

8. Comparison of physiological condition and defense mechanisms of eastern oyster populations with natural Dermo resistance (ODRP, Sea Grant, NOAA, USA)
