Dr. Murray has 8 years experience investigating the interactions between environmental bacteria, metals, and mineral surfaces, and determining the role these play in the fate of contaminant metals.
Dr. Murray has published peer-reviewed papers on the potential for biological oxidation of Cr(III) to the more toxic Cr(VI) in marine and freshwater systems, as well as biological Mn oxidation, Co oxidation, and Hg methylation. She has experience in field sampling in marine, freshwater, and soil systems. Her analytical expertise includes aerobic and anaerobic microbial culturing techniques, electrochemical and spectroscopic chemical analyses, and molecular biological methods.
Dr. Murray has studied the changing toxicity of metals to bacteria under various environmental conditions, and participated in the University of California Toxic Substances Research and Teaching program. She has reviewed journal publications and research grant proposals on environmental metal contaminants and water quality projects.
