About the Team

Gretchen Bielmyer-Fraser      Gretchen Bielmyer-Fraser, Ph.D.

           Professor of Chemistry; Director of Millar Wilson Laboratory

My primary research interests are in the field of Environmental Toxicology with a focus on aquatic systems. Specifically, my research examines how organisms respond to contaminant (particularly metals) exposure, and analyzes the complex interactions between metals and other chemical components in aquatic systems. Mechanisms of toxicity and effects may differ depending on contaminant exposure route, exposure duration, water chemistry and physiology and sensitivity of the organism. Characterizing how these variables interact to influence toxicity at the organism (survival, growth, reproduction), physiological (ion transport, acid-base balance), and biochemical (enzyme activity) levels are central components of my current and future planned research.
