He was a staff member at the Aerospace Corporation (1996-1999)-US Federal Funded Research and Development Corporation and a task manager at JPL/NASA (1999-2007) in US, leading a number of space-related projects including Mars Missions such as Phoenix. He was a recipient of JPL Spot Award (2005). During his career in US, he has led a number of the projects sponsored by DARPA, AFOSR, DOE, NASA, Amy Lab, NSF, NIH, etc. He was director of the Materials Engineering program at University of Idaho in US (2007-2013). He was Founding Department Head of the Mechanical and Materials Engineering (2013-2016) and Founding Space Program Management (2015-2016) at Khalifa University of Science and Technology. Currently, he serves as Director of Khalifa University-KAIST (South Korea) Joint Research Center and Associate Professor of Mechanical Engineering at Khalifa University of Science and Technology. His research focuses on energy storage devices (batteries and capacitors) and inertial sensors (MEMS gyroscopes and accelerometers) for space applications.
