Biography

Dr. Yoseph Bar-Cohen, JPL, is a Senior Research Scientist, the supervisor of the Electroactive Technologies Group (x355N), as well as in-charge of the Nondestructive Evaluation and Advance Actuators (NDEAA) Lab that he established in 1991. He received his Ph. D. in Physics (1979) and M.Sc. in Materials Science (1973) from the Hebrew University, Jerusalem, Israel.  He is a physicist specializing in electroactive materials/mechanisms (including sample handling technologies), biomimetics and ultrasonic Non-Destructive Evaluation (NDE).  He is listed as Subject Matter Expert (SME) in NDE as well as Piezoelectric Actuators and Sensors on the JPL’s Procurement Quality Assurance List. Under his leadership, many innovative concepts and mechanisms were initiated, analytically modeled, simulated, developed, and experimentally tested for planetary exploration, commercial, medical, and other applications.  He made two notable discoveries of ultrasonic wave phenomena in composite materials: the polar backscattering (1979) and the leaky Lamb waves (LLW) (1983).  From Nov. 2009 to Sept. 2011, he served as the Chair of the JPL’s Senior Research Scientists Council.  Dr. Bar-Cohen is a Fellow of two technical societies: The International Society for Optical Engineering (SPIE) and the American Society for Nondestructive Testing (ASNT)
