Research Interests

My research focuses on the ways in which the chemical and physical behavior of aquatic pollutants affects their fate and bioavailability to marine organisms.

Current Projects
  • Development of antibody based biosensors for the quantitative measurement of environmental contaminants
  • Evaluation of TBT accumulation and related effects in a gastropod species. 
  • Conducting laboratory and field studies to help understand relationships between sediment contamination, bioaccumulation and adverse biological effects in feral fish. 
  • Long-term monitoring of the fate and effects of TBT and Kepone in Chesapeake Bay.

Collaborative / Interdisciplinary Efforts

I am currently collaborating with Dr. Steve Kaattari (VIMS) and Dr. Erin Bromage (U Mass) on the production of antibody-based biosensors for the quantification of aquatic contaminants in environmental samples. VIMS graduate student Candace Spier is working with us and focusing her dissertation research on the development of antibody biosensors for detection of small aromatic hydrocarbons, as they are important compounds found in the water-soluble fractions derived from oil.
