Honored by:

Dr. Yoseph Bar-Cohen is a physicist specialized in ultrasonic nondestructive evaluation (NDE) and electroactive materials and mechanism. He received his Ph.D. in Physics (1979) M.Sc. in Materials Science (1973) and B.Sc. in Physics from the Hebrew University, Jerusalem, Israel. He is Senior Research Scientist, Group Leader and the Resident NDE Expert at the Jet Propulsion Laboratory (JPL) responsible for the NDE and Advance Actuators (NDEAA) Technologies (http://ndeaa.jpl.nasa.gov/). Dr. Bar-Cohen is also an Adjunct Professor at the University of California, Los Angeles (UCLA) and a Fellow of the American Society for Nondestructive Testing (ASNT). Two notable discoveries of Dr. Bar-Cohen are the leaky Lamb waves (LLW) and polar backscattering phenomena in composite materials. In 1991, he established the NDEAA Lab that led to a series of innovative concepts and mechanisms, including an ultrasonic drill that is being considered for planetary exploration missions. Currently, he is responsible for developing an ultrasonic drill, electroactive polymer actuators, piezoelectric motors, piezoelectric pump, ultrasonic NDE methods, real time sensing, geophysical probing techniques, haptic interfaces, and high power ultrasonic techniques. His scientific and engineering accomplishments have earned him the 2001 NASA Honor Award: NASA Exceptional Engineering Achievement Medal, and the 2001 SPIE’s NDE Life Time Achievement Award.
