Elizabeth S Clark

Elizabeth S. Clark serves as a Contract Specialist within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security’s Office of Procurement Operations. In this role, she manages the full lifecycle of professional, scientific, and technical service acquisitions critical to national security operations. Her responsibilities include developing solicitation documents, conducting market research, evaluating proposals, negotiating contract terms, and ensuring compliance with federal acquisition regulations. She supports mission-critical initiatives in cybersecurity, systems engineering, and physical sciences, ensuring that technical services align with operational readiness and systems integrity goals across DHS components. Clark’s contracting portfolio is primarily composed of non-set-aside acquisitions, with 100% of her awards issued under full and open competition. While no specific contractor relationships are currently identifiable in the dataset, her work consistently engages a broad spectrum of qualified vendors, including large prime contractors and specialized technical firms with expertise in advanced engineering and IT services. Her procurement patterns reflect a focus on performance-based outcomes and rigorous vendor evaluation, fostering transparent, competitive, and accountable contracting practices. Her socioeconomic contracting approach emphasizes full and open competition, with no preference for 8(a), HUBZone, SDVOSB, or other small business set-asides. This reflects a strategic alignment with agency priorities that require specialized technical capabilities often found in the broader market rather than constrained socioeconomic categories. Clark’s primary procurement focus lies in NAICS 541990 (All Other Professional, Scientific, and Technical Services), which encompasses a wide array of R&D, analytical, and technical support services, and NAICS 541519 (Other Computer Related Services), including systems integration, data analytics, and cybersecurity consulting. She routinely procures advanced technical services supporting homeland defense infrastructure, threat analysis platforms, and mission-critical software systems, demonstrating deep expertise in engineering and IT service acquisition.
