Dr. Yoseph Bar-Cohen is the Supervisor of the Electroactive Technologies Group (http://ndeaa.jpl.nasa.gov/) and a Senior Research Scientist at the Jet Propulsion Lab/Caltech, Pasadena, CA. In 1979, he received his Ph.D. in Physics 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. Dr. Kris Zacny is a Senior Research Scientist, Vice President and Director of Exploration Technology Group at Honeybee Robotics. His expertise includes terrestrial and extraterrestrial robotic drilling, excavation, sample handling and processing, geotechnical systems, and sensors. Dr. Zacny received his PhD (UC Berkeley, 2005) in Geotechnical Engineering with an emphasis on Mars drilling, ME (UC Berkeley, 2001) in Petroleum Engineering with emphasis on Drilling and Materials Science, and BSc cum laude (U. Cape Town, 1997) in Mechanical Engineering.
