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
In this special “Best of 2025” episode, Daniel Marrujo revisits three of the most compelling conversations of the year with Tsu-Jae King Liu, Stacie Williams, and Jennifer Buss—women whose work sits at the center of America’s technological, strategic, and scientific future. These are the voices shaping semiconductor innovation, national security thinking, and the next era of space capability. Through moments of challenge, personal turning points, and candid reflection, this episode reveals just how deeply these leaders influence the decisions and technologies that will define the decades ahead.
Daniel takes listeners deeper into the difficult questions each guest confronts: the global competition for technological advantage, the shrinking pipeline of American R&D investment, and the internal battles that shape every career trajectory. From geopolitics and workforce shortages to daylight satellite imaging breakthroughs and the unexpected life choices that led each woman into her field, this episode highlights the problem facing the United States and how to maintain leadership when its greatest challenges require long-term thinking.
Ultimately, their stories point toward a solution that’s both simple and difficult: the United States must commit to cultivating talent, investing in science, and listening to the people doing the work. Working from this, Tsu-Jae King Liu, Stacie Williams, and Jennifer Buss show us what that future can look like.
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.
