Brian E Leininger

Brian E. Leininger serves as Program Manager for the Innovative Experiments Office (IXO) at the Defense Advanced Research Projects Agency (DARPA), where he leads the design, solicitation, and execution of high-risk, high-reward research initiatives aimed at accelerating transformative military technologies. In this role, he oversees the full lifecycle of advanced technology acquisitions—from concept development to contract award and performance management—focusing on breakthroughs in autonomous systems, next-generation computing, bio-integrated platforms, and advanced materials. His procurement strategy aligns with DARPA’s mission to maintain U.S. technological superiority by rapidly transitioning cutting-edge scientific innovations into operational capabilities, often through time-constrained, milestone-driven programs such as VITAL and PICASSO. Leininger maintains strategic partnerships with a select group of high-caliber contractors, including AEROSPACE & COMMERCIAL TECHNOLOGIES, LLC, AMD INTERNATIONAL TECHNOLOGIES LLC, SYSTEMS & TECHNOLOGY RESEARCH LLC, ABBOTT LABORATORIES INC., and PENNSYLVANIA & SOUTHERN RAILWAY LLC. These relationships reflect a preference for specialized research and development firms with proven expertise in defense-critical domains, including microelectronics, biomedical engineering, and advanced logistics. His contracting approach emphasizes technical excellence and innovation over volume, fostering agile, mission-aligned collaborations with organizations capable of delivering novel solutions under demanding timelines. Leininger’s procurement portfolio exhibits a 100% no set-aside preference, indicating a focus on selecting the most technically capable entities regardless of socioeconomic status. This reflects DARPA’s priority on mission-critical performance over socioeconomic compliance, prioritizing capability, speed, and innovation in a highly competitive technical landscape. His technical domain expertise centers on advanced R&D services supporting physical and life sciences, particularly in areas such as neurotechnology, quantum-enabled systems, autonomous control architectures, and bio-hybrid interfaces. The acquisitions he manages typically involve complex, multidisciplinary contracts requiring deep scientific and engineering capabilities, often spanning classified and unclassified research environments to deliver next-generation defense capabilities.
