MICRO JOURNEYS PODCAST
About Dan Marrujo
Daniel Marrujo is a former Chief Strategy Officer and former Director of the Office of Research and Technology Applications (ORTA) at the Defense Microelectronics Activity (DMEA).
Mr. Marrujo began his career at Raytheon Missile Systems in Tucson, AZ., developing missile guidance systems for their advanced programs. He then moved to DMEA, in his hometown of Sacramento, CA., working for the Trusted Integrated Circuit (IC) program office. In conjunction with working on the Trusted IC program, he began working towards the development of DMEA’s reliability capabilities and was selected to lead the National High Reliability Electronics Virtual Center (HiREV).
Mr. Marrujo also established the NRO’s VS&E program which has executed a number of solutions protecting National Security. As a subject matter expert, he has provided his technical expertise in multiple DARPA, IARPA and National Security Space programs. His focus areas are Microelectronics Obsolescence, State of the Art Microelectronics Acquisition, State of the Practice Microelectronics Sustainment, Advanced Packaging, Supply Chain Risk Management, Semiconductor Reliability, Semiconductor Reverse Engineering and Semiconductor Radiation Effects.
In 2016, Mr. Marrujo was selected as DMEA’s Chief Strategy Officer, directly supporting the DMEA directorate. In this position, Mr. Marrujo works with DMEA senior leadership to define and represent the integrated DMEA message and strategic path forward for future engagements.
Latest Episodes
Northrop Grumman Program Manager Brittany Battaglia joins host Daniel Marrujo for a deep dive into the evolution of microelectronics manufacturing, advanced packaging, and the future of on-shore capability in the United States. Brittany shares her winding career path—from business studies and global supply chain into highly technical program leadership—and how her cross-functional experience uniquely positions her to support the needs of today’s rapidly accelerating defense and commercial markets.
In this episode, Brittany details the transformation occurring inside the Northrop Grumman Microelectronics Center (NGMC), the rollout of its open access model, and why packaging and secure on-shore manufacturing have become essential to national security and technological competitiveness. She explains how Northrop’s “FedEx Flow” streamlines historically fragmented processes across fabrication, bumping, dicing, assembly, and testing—reducing complexity, cost, and delays for customers across the defense industrial base and emerging commercial partners.
Ultimately, this conversation reveals how Northrop Grumman is tackling the bottlenecks in microelectronics with speed, state-of-the-art facilities, and a uniquely integrated ecosystem. Brittany outlines how NGMC’s approach delivers faster timelines, repeatable manufacturing, secure handling, and a single point of accountability—offering a scalable solution to one of the nation’s most pressing technology challenges.
The latest episode of Micro Journeys welcomes Colonel Tim Helfrich, a career Air Force officer whose unconventional path—from Purdue ROTC to test pilot school, to leading next-generation air dominance programs—offers a rare look inside the evolution of U.S. airpower. Daniel Marrujo sits down with Col. Helfrich to unpack how the Air Force is transforming faster than ever before, exploring the breakthroughs in autonomy, modular aircraft architectures, and collaborative combat systems reshaping modern warfare. Through personal stories and behind-the-scenes insights, Helfrich reveals how Airmen today navigate shifting threats, emerging technologies, and a new era of acquisition speed.
In this conversation, Daniel guides listeners into the central challenge facing the Air Force: how to stay ahead of rapidly advancing adversaries while fielding capability faster and at scale. Col. Helfrich explains why traditional “one aircraft, one mission” approaches are no longer enough and how unmanned systems, open architectures, and human-machine teaming are redefining what’s possible. His personal journey underscores the stakes—highlighting both the constraints of old systems and the promise of modular, autonomous, and rapidly upgradable platforms.
Ultimately, the episode outlines a clear solution: move toward a flexible, system-of-systems framework that allows rapid integration, accelerated autonomy development, and collaborative pairing of manned and unmanned aircraft—giving Airmen the adaptability they need to counter today’s evolving threats.
In this episode of Micro Journeys, host Daniel Marrujo sits down with Dr. Alan Mantooth, Distinguished Professor at the University of Arkansas and a leading figure in power electronics and semiconductor innovation. Fresh off a milestone week for the university, Alan gives Daniel an inside look at MUSIC — the Multi-User Silicon Carbide Research and Fabrication Laboratory — a first-of-its-kind facility designed to bridge the long-standing gap between R&D and low-volume silicon carbide production. Together, they explore how this new national asset is reshaping semiconductor access, accelerating innovation, and preparing the next generation of engineers and technicians.
In the conversation, Daniel and Alan dig into the acute challenges facing the U.S. semiconductor ecosystem—from limited access to silicon carbide prototyping, to workforce shortages created by mass retirements and shrinking STEM enrollment. Alan explains why MUSIC fills a critical national void and how its design, educational mission, and partnerships position it as a backbone for future military, commercial, and research advancements. Ultimately, the episode reveals how MUSIC delivers a solution: a fully accessible, production-capable SiC fab that empowers students, startups, researchers, and established manufacturers alike. With hands-on learning, nation-spanning training programs, and compatibility with high-volume foundries, MUSIC stands as a transformative model for U.S. semiconductor resilience and growth.
