Dr. Keller’s research expertise focuses on environmental toxicology in marine and estuarine habitats with an emphasis on protected species. She has expertise in contaminant concentrations, potential adverse health effects of contaminants, and conservation biology, particularly related to sea turtles. Her present research goal is to expand the current knowledge of contaminant concentrations and effects in sea turtles and other marine/estuarine species, especially contaminants of emerging concern, such as brominated flame retardants and perfluorinated compounds.
Prior to coming to NIST as a National Research Council post-doctoral fellow in 2003, Dr. Keller performed her dissertation research on the concentrations of polychlorinated biphenyls (PCBs) and organochlorine pesticides in loggerhead sea turtles and how these compounds may impact their immune and endocrine systems. At NIST, she has expanded this research and now leads the Biological and Environmental Monitoring and Archival of Sea Turtle tissues (BEMAST) project for the NIST Marine Environmental Specimen Bank. She has authored 40 peer-reviewed publications and holds adjunct/affiliate positions at the College of Charleston and Hawaii Pacific University.
