Alexandra Buck

Alexandra Buck serves as a Contracting Officer at the National Institutes of Health, where she plays a pivotal role in securing mission-critical research capabilities that advance biomedical science. She manages the full lifecycle of complex acquisitions for high-precision laboratory instrumentation, specialized biotechnology reagents, computational software, and technical services essential to hypothesis-driven research and clinical translation. Her portfolio supports NIH’s core mission of enabling cutting-edge life sciences innovation through strategic procurement of analytical tools and data-intensive technologies, ensuring compliance with federal acquisition regulations while aligning acquisitions with scientific priorities. Buck maintains consistent, high-volume relationships with leading contractors including Leidos Biomedical Research Inc., Kelly Services, Inc., Fors Marsh Group LLC, PPD Development LP, and The Whiting-Turner Contracting Company. These partnerships reflect a focus on integrated research support services, clinical trial management, laboratory operations, and facility construction for biomedical research environments. Her contracting approach emphasizes performance-based outcomes, technical rigor, and long-term vendor collaboration to ensure continuity in mission-critical research operations. Buck’s procurement patterns show a strong preference for open, non-set-aside competitions, with 100% of her awards issued under unrestricted solicitations. While she does not currently utilize socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB programs, her contracting strategy prioritizes technical capability and scientific alignment over socioeconomic categorization, ensuring the highest quality and most responsive solutions for NIH’s complex research needs. Her primary NAICS focus lies in research and development services across the life sciences—specifically 541715, 541712, and 541714—reflecting deep expertise in procuring physical, engineering, and biotechnological R&D services. She also frequently engages testing laboratories under NAICS 541380, underscoring her specialization in analytical validation, quality control, and clinical assay services essential to translational research and regulatory compliance.
