Origins & Education
Nacer Chahat was born in Angers, France, to a family of Algerian origin. His academic journey began at Lycée Palissy before pursuing higher education. In 2009, he simultaneously obtained a Master's degree in Electrical Engineering from the École Supérieure d'Ingénieurs de Rennes (ESIR) and a Master's degree in Telecommunications from the Institute of Electronics and Telecommunications of Rennes (IETR) at the University of Rennes 1, where he graduated as valedictorian with summa cum laude honors.
His academic excellence led him to pursue a Ph.D. in Signal Processing and Telecommunications at IETR, University of Rennes 1, which he completed in 2012 with summa cum laude honors. His doctoral dissertation focused on "antenna, propagation, and interaction with the body for body-centric wireless communications at microwaves and millimeter-waves." He subsequently completed a postdoctoral fellowship at the prestigious California Institute of Technology (Caltech), marking the beginning of his American career.
Scientific Career
Nacer Chahat's professional career truly began in 2013 when he joined NASA's Jet Propulsion Laboratory (JPL) as a microwave/antenna engineer. His expertise and skills allowed for rapid advancement within the institution: in 2017, he became a technical staff member and product delivery manager, and in 2019, he was promoted to payload system engineer for the SWOT (Surface Water and Ocean Topography) mission.
At JPL, Nacer Chahat has made significant contributions to several iconic space missions, including:
- The Mars Helicopter "Ingenuity," the first aircraft to achieve controlled, powered flight on another planet
- The Mars 2020 mission and its Perseverance rover
- The SWOT mission for Earth observation
- The Europa Clipper mission to explore Jupiter's moon
- Mars Cube One (MarCO), the first CubeSats to operate in interplanetary space
- RaInCube, a technology demonstrator for precipitation observation
A particularly notable moment in his career occurred on April 19, 2021, when he participated, as part of the JPL team, in Ingenuity's historic flight on Mars, demonstrating for the first time the possibility of powered, controlled flight in the atmosphere of another planet.
His research primarily focuses on antenna design and electromagnetic interference/compatibility (EMI/EMC) analysis for space missions. He works across a wide range of frequencies, from UHF to THz, with applications in communications, radar, imaging systems, satellite telecommunications antennas, wearable and flexible antennas, as well as antennas for remote sensing and radio astronomy.
Among his notable technical contributions are the design of the Ka-band deployable reflector for RaInCube, X-band antennas for Mars Cube One, the antenna for the Europa lander, and communication devices for the Mars Helicopter mission.
