Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Natalie Karouna-Renier, Ph.D.


Natalie Karouna-Renier is a Research Ecologist at the USGS Patuxent Wildlife Research Center, in Beltsville, MD, where she is the leader of the Molecular Toxicology Laboratory. Natalie's expertise lays in understanding, detecting, and predicting the effects of environmental stressors on birds and other wildlife, primarily at the molecular and biochemical level. 


  • PhD in Biology from Rensselaer Polytechnic Institute, Troy, NY 
  • MS in Toxicology from the University of Maryland 
  • BS in Biology from Colgate University, Hamilton, NY

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. http://www.usgs.gov/ecosystems/genetics_genomics/environmental_toxicology_birds.html
