Sammy D. Simpson

David Simpson serves as a Contract Specialist at the Defense Threat Reduction Agency (HDTRA1), where he manages the acquisition of critical scientific, technical, and operational capabilities to counter weapons of mass destruction and emerging national security threats. His role encompasses the full lifecycle of contract execution—from requirements validation and solicitation development to award and performance oversight—ensuring alignment with the agency’s mission to detect, deter, and neutralize chemical, biological, radiological, nuclear, and high-yield explosive threats. He routinely handles complex professional services contracts requiring advanced technical expertise and rapid deployment of innovative solutions. Simpson maintains consistent working relationships with leading technical contractors including TECHTRANS INTERNATIONAL INC, BATTELLE MEMORIAL INSTITUTE, AERIS LLC, APPLIED RESEARCH ASSOCIATES, INC., and AMAZON WEB SERVICES, INC. These partnerships reflect a focus on high-caliber, mission-critical support in areas such as threat modeling, sensor development, data analytics, and cloud-based infrastructure. His procurement approach emphasizes performance-based outcomes, technical rigor, and long-term vendor collaboration to ensure operational readiness and scientific integrity. Simpson’s contracting portfolio is exclusively composed of full and open competitions, with no set-asides for 8(a), HUBZone, SDVOSB, or other socioeconomic programs. This reflects a strategic prioritization of technical capability and mission urgency over socioeconomic preferences, aligning with HDTRA1’s need for specialized, non-diluted expertise in high-consequence domains. His primary procurement focus lies in NAICS 541990 (All Other Professional, Scientific, and Technical Services), which encompasses advanced research, analytical services, and systems integration for threat mitigation. He also frequently procures specialized aerospace components under NAICS 336413 and digital content services under NAICS 511210, demonstrating deep engagement in defense science, sensor technology, and secure information systems. His expertise centers on acquiring cutting-edge capabilities that bridge scientific innovation with operational deployment in high-threat environments.
