Water is a natural resource essential to all forms of life, including humans. Quality and supply (quantity) of water are fundamental to healthy ecosystems and sustainable societies. However, our water resources are limited and often under stress as the result of over-allocation, over-development, careless or uninformed practices, and changes to regional climate.  Within the context of aquatic toxicology, my research focuses on the response of aquatic organisms, communities and ecosystems to changes in water and sediment quality (e.g., increased nutrient concentrations or concentrations of substances hazardous to aquatic life) resulting from industrial, agricultural and municipal activities. With respect to contaminants, I am particularly interested in:

  • The bioavailability and toxicity of metals, including nanomaterials, in surface waters and sediments; 
  • Deriving environmental quality criteria (water, sediment, and tissue-based);
  • Aquatic ecotoxicology; and,
  • Aquatic paleoecotoxicology (the reconstruction and interpretation of toxicant-induced changes in ecosystems).
