Biography The 1960s space race led David Winyard to study engineering, beginning in high school at Baltimore Polytechnic Institute. During college, he worked as a co-op at a US Navy research and development (R&D) lab. Through the end of the Cold War, he worked as an engineer on hydraulic systems and pumps for navy ships and submarines, earning five patents in the process. Later, at the Defense Logistics Agency (DLA), Winyard led value engineering projects to cut weapon system costs. He returned to R&D as technical manager for an Advanced Concept Technology Demonstration (ACTD). The three-year ACTD and a follow-up project produced a deployable distribution center, the DDXX, that has supported military, humanitarian, and disaster relief operations worldwide. After retiring, Winyard led the launch of engineering studies at Mount Vernon Nazarene University (MVNU). Later he taught and supported the engineering program rollout at Grace College. Both programs have achieved ABET accreditation. Today, Winyard’s focus is science-faith integration, especially how biblical Christianity speaks to emerging technologies. He encourages Christians to actively shape our technology-saturated world.
