Nacer Chahat received his Master’s degree in electrical engineering from the Ecole Supérieur d’ingénieurs de Rennes (ESIR), Rennes, France, in 2009; the Master’s degree in telecommunication and the Ph.D. degree in signal processing and telecommunications from the Institute of Electronics and Telecommunications of Rennes (IETR), University of Rennes 1, Rennes, France, in 2009 and 2012, respectively. He is a Senior Antenna/Microwave Engineer with the National Aeronautics and Space Administration (NASA) Jet Propulsion Laboratory (JPL), California Institute of Technology, Pasadena, CA. Since 2013, he has been a Microwave/Antenna Engineer with NASA’s Jet Propulsion Laboratory and he has been Technical Section Staff and Product Delivery Manager since 2017. He has authored and co -authored more than 100 technical journal articles and conference papers. He has written four book chapters, and also holds several patents. He also wrote the textbook entitled “CubeSat Antenna Designs” published by Wiley describing all of his innovative work on CubeSat antennas developed at JPL. He has developed key antenna technologies enabling new types of mission for Deep Space Exploration. He is co-inventor of the iconic deployable reflectarray used on the Mars Cube One (MarCO) mission, the world’s first interplanetary CubeSat. He also co-invented the award-winning Raincube mesh reflector antenna used on the first active radar on a CubeSat. He also invented the Europa Lander antenna enabling direct communication from the surface of Europa (600 million km away), capable of surviving the harsh environment of the icy moon of Jupiter. Dr. Chahat was the recipient of the 2011 CST University Publication Award, the 2011 Best Paper Award from the Bioelectromagnetics Society, and the IEEE Antenna and Propagation Society Doctoral Research Award in 2012. He was awarded the Foundation of Rennes 1, Best Ph.D. of University of Rennes. In 2013, he received the Best Ph.D. thesis in France in electrical engineering awarded by club EEA. In 2013, he was awarded the Airbus Group Foundation’s Best Thesis Prize in France. In 2015, he received a French Early Career Award for Researchers (Prix Bretagne Jeune Chercheur) for his significant scientific contribution in his early career. In 2017, he received the IEEE A. Schelkunoff Transactions Prize Paper Award. In 2017, he also received the prestigious Lew Allen Award for Excellence awarded by NASA’s Jet Propulsion Laboratory “for demonstrated unique talent as a leader in rapid spacecraft antenna development and telecom systems engineering”. In 2018, he was awarded the Future Technology Leader Award by the Engineers’ Council and the NASA Early Career Achievement Medal Award.
