• Ultrasonic nondestructive evaluation of material properties

Experience:

Richard Martin has been employed by UDRI as a research electrical engineer since 1976.  During that time he has worked in the Air Force Research Laboratory’s Materials and Manufacturing Directorate developing and integrating electronic analog and digital systems, developing system-control software, and collecting and analyzing data in the tribology and nondestructive evaluation areas. 

Before joining UDRI, Richard worked for Technology Incorporated as a design engineer, integrating hardware and software that linked sensors to a computer system on one of the first automated jet-engine test cells.  Prior to working for Technology Incorporated, he taught formal courses and conducted laboratory classes on digital computers, industrial electronics, and radio and television systems as an electronics instructor at ITT Technical Institute.
