research overview

Dr. McKnight's research focuses on the interactions between water quality and the aquatic ecology of algae and other aquatic organisms in lakes and streams. An important aspect of her work is understanding the biogeochemical processes controlling the chemistry of natural organic material and trace metals in freshwater systems. Her field research is conducted in alpine and polar environments, including the Colorado Mineral Belt and the McMurdo Dry Valleys of Antarctica.
