Deborah D Iwanowicz



Dr. Deborah D. Iwanowicz is a research biologist that has been trained in molecular diagnostics. Her research principally involves that pertaining to next-generation sequencing incorporated within and beyond the infectious and non-infectious diseases of fish. She is a principle investigator and collaborator on a number of projects involving the effects of contaminants on fish health, the spread of diseases with invasive species, investigating complex microbial communities, and protocol/assay development. Her research includes that of molecular microbiology (parasitology, bacteriology, virology on fishes, amphibians, sea turtles, marine mammals, insects, plants, aquatic and terrestrial gastropods). She leads efforts in the NFHRL for method development on metagenomics analyses of diet from scat, stomach content, or fecal pellets. This work has been modified to identify plant species found in pollen, diets of terrestrial endangered animals, birds, and aquatic animals.

Dr. Iwanowicz received her undergraduate degree in Wildlife Science (minors in Spanish and Anthropology) from Purdue University (West Lafayette, IN), her M.S. in Aquatic Nutrition at Purdue University (West Lafayette, IN) and her Ph.D. in Parasitology/Toxicology at the University of Georgia (Athens, GA). Dr. Iwanowicz joined the U.S. Geological Survey, Leetown Science Center, National Fish Health Research Laboratory in August of 2000.
