Linda M Mulligan

Linda M. Mulligan serves as a Contracting Officer within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security’s Office of Procurement Operations, where she plays a pivotal role in executing mission-critical acquisitions that support national security and operational readiness. She manages the full lifecycle of professional, scientific, and technical service contracts, ensuring compliance with federal acquisition regulations while advancing research, cybersecurity, and systems engineering capabilities essential to DHS’s core missions. Her portfolio primarily encompasses complex, high-stakes procurements requiring specialized technical expertise, including engineering analysis, scientific R&D, and technical consulting services. Linda collaborates with a diverse range of contractors, including large professional services firms and mid-tier technical consultants, to secure mission-ready solutions across physical and engineering sciences. While no single contractor dominates her portfolio, she maintains a consistent pattern of engaging vendors with proven capabilities in systems integration, laboratory services, and applied research. Her working relationships emphasize performance-based outcomes, rigorous contract administration, and adherence to technical specifications, fostering long-term partnerships grounded in accountability and innovation. Linda’s contracting activity reflects a strong preference for full and open competition, with 100% of her awards issued without set-asides, indicating a focus on technical merit and capability over socioeconomic classifications. While she does not routinely utilize 8(a), HUBZone, or SDVOSB set-asides, her approach prioritizes mission effectiveness and access to the broadest possible pool of qualified vendors to meet complex technical demands. Her primary procurement focus lies in NAICS 541990 (All Other Professional, Scientific, and Technical Services) and NAICS 541712 (Research and Development in the Physical, Engineering, and Life Sciences), with significant activity in technical consulting and chemical supply services. She specializes in acquiring advanced scientific instrumentation, engineering analysis, cybersecurity research, and applied R&D services critical to maintaining the integrity of DHS’s technological infrastructure and operational systems.
