Christopher Wallis

Christopher Wallis serves as a procurement professional within the Contract Administration Services Division of the Department of Homeland Security’s Office of Procurement Operations, where he plays a critical role in managing the acquisition of professional, scientific, and technical services essential to national security operations. His responsibilities include overseeing the full lifecycle of contracts for research, systems engineering, and management consulting services that enhance operational readiness and infrastructure integrity. Wallis specializes in complex service-based procurements under FAR Part 12 and Part 37, ensuring compliance with federal acquisition standards while aligning acquisitions with DHS’s strategic priorities in cybersecurity, physical sciences, and engineering innovation. Wallis maintains collaborative relationships with a diverse pool of contractors, primarily engaged in consulting, technical analysis, and scientific support services. While no single vendor dominates his portfolio, he consistently engages with firms possessing specialized expertise in systems engineering, policy research, and operational analytics. His contracting approach emphasizes performance-based outcomes, rigorous evaluation of technical proposals, and adherence to merit-based selection criteria, fostering a competitive environment that prioritizes capability over size. His procurement patterns reflect a strong preference for open competition, with 84.6% of awards issued without set-aside restrictions. Nevertheless, he actively supports small business participation, regularly awarding contracts under Total Small Business Set-Asides (11.5%) and HUBZone programs (3.9%), demonstrating a balanced commitment to socioeconomic goals without compromising mission-critical requirements. Wallis’s primary focus lies in NAICS 541690 (Other Scientific and Technical Consulting Services) and 541611 (Administrative Management Consulting), with significant activity in 541720 (Social Sciences and Humanities Research) and 423450 (Medical Equipment Wholesaling). His portfolio underscores deep expertise in procuring technical advisory services, research-driven solutions, and specialized equipment procurement that directly supports DHS’s mission to safeguard critical infrastructure and advance scientific resilience.
