Dr. Jose V. Siles received the M.Sc. and Ph.D. degrees in telecommunication and electrical engineering from the Technical University of Madrid, Madrid, Spain, in 2003 and 2008, respectively. In 2002, he joined the Signal, Systems and Radiocommunications Department of the Technical University of Madrid as a Research Fellow supported by a fellowship from the Spanish Ministry of Education, working on the physics-based modeling of semiconductor devices for terahertz applications. Part of this research was performed at the University of Rome “Tor Vergata”, Italy, and at the Observatory of Paris-LERMA, France. In 2008 and 2010, he was a Post-Doctoral Fellow with the Observatory of Paris-LERMA participating in several programs funded by the CNES, the European Space Agency and the European Commission. In September 2010, he joined the Submillimeter-Wave Advanced Technology Group at NASA's Jet Propulsion Laboratory, California Institute of Technology, Pasadena CA, USA, as a Fulbright Post-Doctoral Fellow. He has participated in several programs to develop terahertz technology, including frequency multiplied sources and receivers, for the French space agency (CNES), the European Space Agency (ESA), the European Commission and NASA/JPL. He is an experienced terahertz component and circuit designer, having designed and tested terahertz sources and mixer circuits up to 3 THz, all of them exhibiting world-record performances. His current research interests involve the design, development and test of ultra-compact solid-state power-combined multiplied local oscillator sources and receivers for high resolution multi-pixel heterodyne cameras at submillimeter-wave and terahertz frequencies for radio-astronomy, planetary science, Earth science, communications, and radar applications. He was the recipient of a Fulbright Postdoctoral Research Award at JPL for the period 2010-2012, sponsored by the U.S. Department of State and the J. Fulbright Program. In 2015/16 and 2016/17, he was responsible for the delivery, assembly and I&T in Antarctica of the of the first multi-pixel terahertz local oscillator system for NASA’s Stratospheric Terahertz Observatory (STO-2), successfully launched from Antarctica on Dec.2016. He is Principal Investigator of several NASA funded tasks to develop the next-generation of high-spectral resolution submillimeter-wave instruments for Astrophysics and Planetary Science. Dr. Siles was the recipient of the 2012 NASA/JPL Outstanding Postdoctoral Research Award and the 2014 NASA Outstanding Group Achievement Award for the Development of Compact Multi-Pixel Receivers for Planetary Science. He was awarded in 2016 with the U.S. Antarctic Service Medal. In 2018, he received the prestigious JPL Lew Allen Award for Excellence.
Jose is a senior member of IEEE, vice chair of the Metro LA Chapter of IEEE/MTT-S and President of the LA Chapter of the Fulbright Association.
He enjoys playing soccer, swimming, travelling, salsa dancing and flying airplanes. He is an experienced instrument rated private airplane pilot. He has spent a total of 5 months on the ice during two Antarctic scientific balloon campaigns in 2015 and 2016.
He is currently the Project Manager and technical lead of the "The Astrophysics Stratospheric 2.5-m Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths" (ASTHROS) NASA balloon mission, scheduled to launch from Antarctica on December 2023.
