Dr. Yoseph Bar-Cohen is a Senior Research Scientist (SRS), Supervisor of the Advanced Technologies Group and the Chair of the SRS Council at JPL. He received his Ph.D. in Physics (1979) from the Hebrew University, Jerusalem, Israel. His research is focused on electro-mechanics including planetary sample handling mechanisms, novel actuators that are driven by such materials as piezoelectric and EAP (also known as artificial muscles) and biomimetics. In his NDEAA lab (http://ndeaa.jpl.nasa.gov/) he led the development of many novel methods and mechanisms. In the materials called composites, he discovered the ultrasonic wave phenomena polar backscattering (1979) and leaky lamb waves (1983). He co-edited and co-authored 7 books, co-authored over 340 publications, made numerous presentations at national and international conferences, co-chaired 43 conferences, and has 22 registered patents. He initiated the SPIE conference on artificial muscles, which he has been chairing since 1999. Dr. Bar-Cohen challenged engineers and scientists worldwide to develop a robotic arm driven by artificial muscles to wrestle with humans and win. He organized the first contest in 2005. For his contributions to the field of artificial muscles, Business Week named him in April 2003 one of five technology gurus who are Pushing Tech's Boundaries. His accomplishments earned him two NASA Honor Award Medals, two SPIEs Lifetime Achievement Awards, the SPIEs Presidents Award, 72 NASA Tech Brief Awards and many other honors and awards. Also, he is a Fellow of two technical societies: ASNT and SPIE.
