Healthy aquatic resources are essential to sustainable human culture. We use fresh water for nourishment, commerce, transportation and recreation. In the Canadian prairies, periodic lack of freshwater (droughts) restructure the fundamental fabric of our society (e.g., the dirty 30's). My research seeks to understand, quantify and predict changes in water quality using a wide range of empirical, experimental, modelling and paleoecological approaches.
