Research Laboratory, where he did research on laser-induced ionization of high-pressure gases. Later he pursued graduate studies part time at Catholic University of America and earned a master’s of electrical engineering degree in 1973 and a Ph.D. in 1978.
John began a career with the National Aeronautics and Space Administration (NASA) in 1966 at the Goddard Space Flight Center. Over the years he served in various capacities at Goddard, including senior physicist and electronics engineer, head of the Laser Heterodyne Systems Section, and head of the Electro-Optics and Laser Technology branches. He directed research on laser communications systems, tracking and radiometry, and advanced satellite communications technology. From 1979 to 1980, John served as director of the Communications Division, Office of Space and Terrestrial Applications, at NASA Headquarters, where he directed the revitalization of NASA’s communications R&D program. John returned to Goddard in 1980 as deputy director and served in that capacity until 1982.
John served as the assistant administrator for satellites for the National Oceanic and Atmospheric Administration (NOAA) from 1982 to 1985. At NOAA he directed the national program in civil operational earth observation satellites, including responsibilities for Landsats-4 and -5, the Tiros series of polar-orbiting satellites, and the GOES series of geostationary satellites.
John joined Hughes Aircraft in 1985 as director of special projects for the Space and Communications Group. He served as vice president for technology of Hughes Communications from 1986 to 1987. While vice president, John led a corporate venture on mobile satellite communications that later became the American Mobile Satellite Corporation. During this time period, he was also senior editor of Space Science and Applications, a publication of the Institute of Electrical and Electronics Engineers’ Aerospace and Electronic Systems Society.
From 1987 to 1996, John served as dean of the College of Engineering at the University of Texas at Arlington, overseeing
