Yoseph Bar-Cohen

Yoseph Bar-Cohen (Hebrew: יוסף בר-כהן) is a physicist retiree from the Jet Propulsion Laboratory (JPL). He specialized in electroactive materials driven mechanisms and ultrasonic nondestructive evaluation (NDE), and was also responsible for the JPL's [[Nondestructive Evaluation and Advance Actuators] http://ndeaa.jpl.nasa.gov/] (NDEAA) lab. He was formerly a Group Supervisor and a Senior Research Scientist. Bar-Cohen is a fellow of the International Society for Optical Engineering (SPIE) and the American Society for Nondestructive Testing (ASNT) [https://orcid.org/0000-0003-1262-9917],

He has 43 registered patents, edited and coauthored 12 books, co-authored 460+ publications, and co-chaired 56 international conferences [http://ndeaa.jpl.nasa.gov/nasa-nde/yosi/yosi.htm]. Using ultrasonic waves in composite materials, he discovered the polar backscattering (1979) and leaky lamb waves (1983) phenomena [https://orcid.org/0000-0003-1262-9917]

Bar-Cohen received a M.Sc. in materials science in 1973 and a Ph.D. in physics in 1979, both from the Hebrew University in Jerusalem.

Bar-Cohen started SPIE's Electroactive Polymer Actuators and Devices (EAPAD) conference, which he has chaired twenty two times, as well as proposing the Armwrestling Match of EAP Robotic Arm Against Human.
