Barbara K. Marn serves as a Budget & Accounting Assistant within the Agricultural Research Service (ARS) under the U.S. Department of Agriculture, supporting the financial and administrative infrastructure critical to mission-driven research procurement. In this role, she facilitates the alignment of budgetary allocations with acquisition planning, ensuring fiscal compliance and timely execution of contracts for scientific equipment and agricultural inputs. Her work directly enables the procurement of specialized laboratory instrumentation, precision farming technologies, and research-grade supplies essential to advancing crop, livestock, and biosecurity studies. She collaborates closely with program scientists and contracting officers to translate technical requirements into actionable financial documentation, playing a pivotal role in the end-to-end acquisition lifecycle. Barbara maintains a consistent working relationship with McKenzie Construction & Site Development LLC, a primary vendor engaged in facility upgrades and site infrastructure improvements supporting ARS research campuses. Her procurement patterns reflect a reliance on established contractors with proven expertise in laboratory environment modifications, utility enhancements, and compliance-driven construction services. These partnerships are characterized by repeat engagement and a focus on reliability, technical adherence to federal standards, and timely delivery of mission-critical infrastructure support. Barbara’s contracting activity shows no use of socioeconomic set-asides, with 100% of acquisitions conducted under full and open competition. This reflects a strategic emphasis on technical capability and operational readiness over socioeconomic preferences, aligning with ARS’s priority to secure specialized goods and services without restriction. While small business participation is not formally prioritized in her portfolio, her work remains fully compliant with federal procurement regulations and transparency requirements. Her procurement focus centers on construction, facility modernization, and site development services supporting agricultural research infrastructure. Though NAICS data is not available, her acquisitions consistently involve technical domains such as laboratory renovation, environmental controls, and site-specific engineering solutions tailored to biosafety and research integrity standards. Her expertise lies in ensuring that physical infrastructure meets the stringent demands of scientific research environments.
