William N. Li

William N. Li serves as a Senior Contracting Officer at the National Institute of Standards and Technology (NIST), where he leads the acquisition of mission-critical scientific and technical services to advance measurement science, semiconductor standards, and advanced manufacturing capabilities. His portfolio centers on complex R&D contracts supporting federal innovation priorities, including analytical instrumentation, engineering consulting, and laboratory technology procurement. Li ensures compliance with federal acquisition regulations while aligning acquisitions with NIST’s strategic goals in national security, economic resilience, and technological leadership. Li maintains longstanding relationships with key vendors including Quality Biological, Inc., Advanced Technologies and Laboratories (ATL) International, Inc., Physical Electronics USA, Inc., and Airgas USA, LLC, reflecting a preference for specialized providers with deep expertise in laboratory systems, precision instrumentation, and scientific support services. His contracting approach emphasizes technical proficiency, performance reliability, and long-term vendor collaboration, often resulting in repeat engagements with contractors who demonstrate consistent capability in high-stakes, standards-driven environments. His procurement patterns show a strong commitment to small business participation, with nearly half of his awards structured as Total Small Business Set-Asides under FAR 19.5. While no set-aside remains the largest category, Li consistently prioritizes small business eligibility and actively fosters opportunities for small disadvantaged and women-owned firms within NIST’s technical ecosystem, reinforcing the agency’s socioeconomic contracting objectives. Li’s primary NAICS focus areas include 541712 (R&D in physical and engineering sciences), 541690 (scientific consulting), and 334516 (analytical laboratory instrument manufacturing), underscoring his specialization in procuring cutting-edge research tools, engineering services, and precision measurement systems. His expertise lies in acquiring technically complex, high-integrity solutions that support NIST’s role as the nation’s premier standards development authority.
