In this episode of Micro Journeys, host Daniel Marrujo talks with Greg Van Dyk about how a career spanning engineering, program leadership, and entrepreneurship led him to focus on clean energy and advanced manufacturing. Greg shares lessons from large technical programs and explains how modeling, supply chains, and workforce development come together to support resilient U.S. manufacturing.

You’ll hear a practical discussion about semiconductor production efforts, the role of data and verification in complex systems, and why fusion energy research is gaining momentum. We cover how to build partnerships, plan for scale, and translate long-term goals into repeatable processes that deliver reliable results.
