Dr. Davis is a materials consultant with over 30 years of experience in basic and applied research and development involving surfaces and interfaces related to adhesion and corrosion.  Particular areas of interest include surface treatments, especially those improving the durability or corrosion resistance of materials, and nondestructive evaluation or monitoring of material degradation.  He was one of the pioneers in using x-ray photoelectron spectroscopy (XPS) and other surface analytical techniques to understand the degradation of adhesive bonds and to develop processes to improve durability.  Later, he invented of a series of corrosion sensors that allow electrochemical impedance spectroscopy (EIS) to be performed under ambient conditions instead of the hitherto required immersion conditions.  These sensors detect corrosion of painted structures and moisture intrusion and degradation of polymeric materials during accelerated tests and field service.  In addition, he has used his background in surface analysis, electrochemistry, and materials science for process development and failure analysis of manufactured components and processes that enabled improvements in reliability and yield, realization of cost savings, and resumption of production.
