Dr. Glenn A. Washer is a Professor at the University of Missouri (MU) and has worked in nondestructive evaluation (NDE) for bridges for 30 years. Before joining MU in 2004, Dr. Washer was with the Federal Highway Administration (FHWA), where he was program manager for the FHWA NDE program. Dr. Washer received his undergraduate degree at Worcester Polytechnic Institute in 1990 and a master of science degree in structural engineering at the University of Maryland, where he studied time-of-flight diffraction to detect critical flaws in bridges. He received his PhD in Materials Science and Engineering from the Johns Hopkins University Center for Nondestructive Evaluation (CNDE) in 2001 under the direction of Dr. Robert Green, where he studied the acoustoelastic effect in bridge tendons. He has published more than 120 journal and conference papers on the condition assessment of bridges and is an ASNT Fellow.
