Euan Reavie Ph.D.

Professional Title
Sr. Research Associate, Interim Water Team Leader

Dr. Reavie is a Senior Research Associate. Euan and his research team pursue research in applied aquatic studies on freshwater ecosystems, evaluating water quality issues. Routine work focuses on the use of algae as indicators of environmental changes. Their laboratory is fully equipped for research on biological and chemical indicators of water quality, and paleolimnology, the study of environmental trends through the analysis of sediment profiles. Techniques include high-resolution microscopy, digital imaging, laboratory processing and field sampling.

Recent Studies

  • Development of environmental quality indicators in the Great Lakes using algal communities;
  • Tracking long–term pollution trends using fossil remains in sedimentary profiles from northern Minnesota;
  • Assessing the efficacy of potential ballast water treatments intended to prevent non–native species introductions to the Great Lakes; and,
  • Long–term monitoring of Great Lakes phytoplankton responses to stressors, including nutrient enrichment and climate change.
