Paul Sollock began his NASA career in September 1962 as a cooperative education student at the University of Houston. Upon receiving his BSEE in June, 1965 he accepted a position in the Guidance & Control Division at the Manned Spacecraft Center. From that time until 1970, he was involved in testing of the Apollo Digital Autopilot during which he developed a familiarity with the emerging technology of digital computers. During the early 1970's, he was lead engineer for several in-house test bed projects that evaluated redundant flight computer architectures using the new multiplexed digital data bus technologies for Input/Output. The success of those evaluations was instrumental in NASA management accepting the relatively unproven technologies for the Shuttle. Upon formal approval of the Shuttle Project, Paul Sollock was assigned as (SSM)Subsystem Manager of the Shuttle's General Purpose Computer in 1974. He remained in that position through the first Shuttle Flights. In 1981 he became a first line supervisor (Section Head) of SSMs for the various hardware elements comprising the Shuttle core Avionics. Subsequently, he held management position of increasing responsibility, including Division Chief of the Avionic Systems Division - a position he held from 1995 to his retirement in October 1999. He is now employed as a Consultant for Geologics, Inc. In that capacity, he is subcontracted to USA in the role of technical manager for Validation and Verification of the CAU (Cockpit Avionics Upgrade) Project.
