Stephanie C. D'Anniballe

Stephanie C. D’Anniballe serves as a key procurement lead at NASA Glenn Research Center, where she manages complex acquisitions supporting advanced aeronautics and space propulsion technologies. Her work is central to the Center’s mission of developing next-generation power systems, thermal management solutions, and aerospace instrumentation for lunar and planetary exploration. She oversees a diverse portfolio of contracts spanning engineering services, semiconductor equipment, and specialized training programs, ensuring alignment with NASA’s technical priorities and federal acquisition regulations. Her acquisitions are mission-critical, enabling the development of fission surface power systems and extreme-environment materials that underpin future deep-space missions. D’Anniballe maintains strategic relationships with a select group of high-specialization contractors, including Troy Sierra JV LLC, Aerospace & Commercial Technologies, LLC, and Electronic Fluorocarbons, LLC, each providing niche capabilities in propulsion subsystems, advanced materials, and thermal fluid systems. Her contracting patterns reflect a preference for established technical partners with proven expertise in aerospace engineering and high-reliability manufacturing, fostering long-term collaboration on technically demanding, low-volume procurements. These partnerships are characterized by deep technical engagement and rigorous performance oversight. Her procurement approach prioritizes competitive open market acquisitions, with 72.7% of awards issued without set-aside designations, yet she consistently integrates small business participation, allocating 27.3% of contracts through the 8(a) program. This reflects a balanced commitment to innovation and socioeconomic goals, ensuring that qualified small businesses contribute to high-stakes aerospace development while maintaining technical rigor. D’Anniballe’s primary NAICS focus lies in Semiconductor Machinery Manufacturing, Engineering Services, and Professional and Management Development Training, each representing 27.3% of her portfolio. She procures precision manufacturing equipment for semiconductor fabrication, specialized engineering analyses for propulsion systems, and workforce development programs in advanced aerospace technologies. Her domain expertise centers on mission-critical systems requiring stringent reliability standards, including high-temperature materials, cryogenic fluid handling, and radiation-hardened electronics.
