William M. Davis received his BSc (honors) in chemistry from the University of Western Ontario, London, Canada, and his MSc and PhD from the University of Guelph, Ontario, Canada. He taught lecture and laboratory sections of general, physical, and inorganic chemistry at several Canadian universities before moving to Texas to take up a tenure-track position at The University of Texas at Brownsville, where he taught general, physical, inorganic, analytical, organic, and environmental chemistry for 10 years. In 2008, he moved to Texas Lutheran University, where he is currently an Associate Professor and Chair of Chemistry and holds the George Kieffer Fellowship in Science. Dr. Davis's research interests include application of computational and analytical chemistry techniques to systems of environmental and biochemical interest.
