Jeffrey Eldridge received a B.A. in physics from the University of Chicago and a Ph.D. in physics from Case Western Reserve University. Dr. Eldridge was a Research Associate at the National Research Council of Canada for three years where he conducted research into the thermal oxidation of aluminum and aluminum-containing alloys. In a NASA career spanning over twenty years, Dr. Eldridge has worked towards developing spectroscopy-based health monitoring tools for both space and turbine engine applications. These efforts have included developing tests to evaluate interfacial strength in fiber-reinforced composites, Raman-based strain measurements for pressure vessels used on the space shuttle, and more recently developing luminescence sensing and mid-infrared reflectance imaging for health monitoring of thermal barrier coatings used in turbine engine applications. He has coauthored over 70 publications and has made over 50 conference presentations and invited tutorials/lectures. Dr. Eldridge is a senior scientist of the Optical Instrumentation and NDE Branch at NASA Glenn Research Center.
