RESEARCH INTERESTS
Biomarkers of environmental stressors; Comparative Immunology
RESEARCH IN PROGRESS
The overall goal of my research is to provide
scientific information that contributes to
decision-making on the management of
the Nation's natural resources. With a background in comparative immunology as
well as microbial virulence mechanisms and host responses, my primary research
focus at the
National Wetlands Research Center, Biological Resources Division, U.S.
Geological Survey is on cellular and molecular responses of animal cells to
environmental stressors. Animal models include teleosts, invertebrates,
amphibians, and birds, whereas stressors include contaminants, bacteria, and
poor water quality. My studies emphasize the development of bioindicator assays,
often using flow cytometry with blood, hemocyte, or sperm cells, to be used in
conjunction with established
USGS-approved methods.
