Onoufrios Theofylaktos is a research engineer at the National Aeronautics and Space Administration's Glenn Research Center at Lewis Field in Cleveland, Ohio. He is currently working on imaging and electrical characterization of polymer-based nanowires in cooperation with the University of Puerto Rico (DDF/IRAD). He is also working on the ACAST (Advanced Communication, Navigation and Surveillance Architectures and System Technologies) project with the Federal Aviation Administration and as a technical monitor on self-modulating phased-arrays for satellite communications with Cleveland State University.

Mr. Theofylaktos earned his master of science degree in electrical engineering from Cleveland State University in 1987. He previously worked on several projects associated with the Advanced Communications Technology Satellite (ACTS), some in cooperation with Virginia Polytechnic Institute and the Jet Propulsion Laboratory. He also designed, built, tested, and delivered a 30-GHz up-down converter for the D3 Project; designed and built the Olympus scintillation terminal in cooperation with Virginia Polytechnic Institute for the purpose of acquiring and analyzing 30-GHz scintillation data at low elevation angles; upgraded the position controller and laser measurement system at the Glenn Near-Field Antenna Scanner Facility; and researched holographic information storage based on ferroelectric films.
