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 episode of Micro Journeys, host Dan Marrujo takes listeners deep inside one of the most secure and mysterious facilities in the United States — a Department of Energy lab where scientists are literally recreating the power of the sun. Joined by Larry Phair, veteran staff scientist at the Lawrence Berkeley National Laboratory, the conversation opens the blast doors to a world where cosmic rays, heavy ions, and cutting-edge nuclear science collide. From testing the endurance of satellites bound for orbit to exploring the edges of the periodic table, this episode blends wonder, engineering, and humanity’s relentless quest for discovery.
At its core, this episode explores a bigger question: how does humanity build and test the technology that keeps our modern world — and our space exploration — alive? Larry explains how the cyclotron, once a relic of mid-20th century nuclear research, has evolved into a Swiss-Army knife for modern science. The discussion sheds light on how his team simulates radiation from space, creates beams from nearly every element in the periodic table, and pushes forward the search for entirely new elements — all from inside a bunker that most people will never see.
Ultimately, the solution is a story of precision and persistence: by recreating the universe’s harshest environments inside controlled walls, scientists like Larry are helping humanity build technology strong enough to survive beyond Earth.
In this episode of Micro Journeys, host Daniel Marrujo sits down with Dave Shahin of Northrop Grumman to explore the cutting-edge world of microelectronics and advanced packaging. From his early fascination with building things to his current leadership role at Northrop Grumman’s Microelectronics Center, Dave shares a journey that spans from ceramic engineering to semiconductor innovation — and ultimately to shaping the future of defense and commercial technology.
Diving deeper, Dave discusses the critical role advanced packaging plays in connecting and integrating semiconductor components, enabling greater performance, miniaturization, and reliability. He explains how Northrop Grumman’s open-access manufacturing model is reshaping the U.S. defense and commercial landscape — creating trusted, onshore capabilities that bridge national security needs with commercial innovation.
Ultimately, Dave reveals how Northrop Grumman is building a secure, scalable microelectronics ecosystem that partners across the industry to meet national priorities. Through flexibility, scale, and collaboration, the company is ensuring America’s semiconductor independence and leadership in next-generation technologies.
Admiral James Bynum joins host Daniel Marrujo for an extraordinary deep dive into a life defined by service, leadership, and transformation. From his early fascination with aviation to commanding F/A-18 squadrons, serving on Capitol Hill with Senator John McCain, and working within the White House Military Office, Admiral Bynum’s journey charts how purpose and adaptability can span from cockpit to Congress to the frontier of artificial intelligence. His story offers a window into the evolution of warfare, the complexity of decision-making, and the enduring human element at the center of it all.
In this episode, Daniel and Admiral Bynum explore how technology is reshaping the landscape of defense and leadership. The conversation moves from the intensity of night carrier landings to the intricate world of military policy and the growing power of AI-driven decision systems. Along the way, Admiral Bynum reflects on the challenges of transition—how a lifelong commitment to national service evolves after retirement, and what it means to lead through both uncertainty and innovation.
Ultimately, Admiral Bynum leaves listeners with a vision for the future: warfare executed at the speed of compute, where humans move from being in the loop to on it—trusting data, algorithms, and purpose-built systems to act with precision while preserving human judgment for when it matters most.
