William Barrington

William Barrington serves as a key procurement professional at NASA’s Johnson Space Center, supporting the agency’s mission to advance human spaceflight systems and life sciences research. He manages complex acquisitions for research and development services in physical, engineering, and life sciences, with a focus on enabling crewed missions to low Earth orbit, the Moon, and beyond. His work centers on securing technical expertise for spacecraft guidance, microgravity physiology, and radiation biology studies, ensuring mission-critical capabilities are developed and integrated under federal contracting frameworks. Barrington handles competitive and sole-source procurements for high-stakes R&D contracts requiring specialized scientific and engineering proficiency. His primary contractor relationships include Sierra Space Corp, Aspera Biomedicines, Inc., and Single Crystal Diamond Inc., reflecting a focus on innovative aerospace, biomedical, and advanced materials solutions. He consistently engages with firms possessing deep domain expertise in human spaceflight systems, life support technologies, and space-qualified instrumentation. These partnerships are characterized by long-term collaboration, technical alignment with NASA’s strategic priorities, and a preference for vendors with proven experience in extreme-environment research and development. Barrington’s procurement portfolio shows no use of socioeconomic set-asides, with 100% of awards issued under full and open competition. This reflects a mission-driven emphasis on technical capability over socioeconomic criteria, prioritizing the most qualified entities capable of delivering cutting-edge solutions under stringent spaceflight requirements. While small business participation is not formally incentivized through set-asides, vendors of all sizes compete on technical merit and past performance. His procurement activity is exclusively classified under NAICS 541715, indicating a laser focus on research and development in the physical, engineering, and life sciences. He procures advanced laboratory equipment, computational modeling services, life science experiment hardware, and spacecraft systems integration support—all tailored to the unique demands of human space exploration. His expertise lies in navigating the intersection of federal acquisition regulation and high-risk scientific innovation.
