Research Interests:

Research in Natalie's lab centers on the identification and application of novel genomic and non-genomic indicators for identifying toxicological responses in wildlife. The effects of endocrine active and genotoxic compounds, and the development of tools to assess and predict differences in species sensitivity are of particular interest and focus.  Natalie has also conducted multiple studies investigating higher level effects of contaminants on wildlife, fish, aquatic invertebrates, and humans.
