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 and Vice President of Exploration Technology Group at Honeybee Robotics, Altadena, CA. His expertise includes terrestrial and extraterrestrial robotic drilling and mining, sample handling and processing, geotechnical systems, and sensors. Dr. Zacny received his PhD from UC Berkeley (2005) in Geotechnical Engineering with focus on planetary drilling and space mining, ME from UC Berkeley (2001) in Petroleum Engineering, and BSc cum laude from U. of Cape Town (1997) in Mechanical Engineering. He spent several years working in South African mines and tested space drills in Antarctica, Arctic, Greenland, and the Atacama.
