Rogan Shimmin is the Energy & Power Challenge Manager at NATO DIANA, the Defence Innovation Accelerator for the North Atlantic. In this capacity he manages and mentors 14 companies from the pilot year cohort including three selected for the GROW phase follow-on, and recently led the selection of 15 new companies for the 2025 program from over 2600 applicants. Born in Adelaide, Australia, Rogan earned undergraduate degrees in mechatronics engineering, mathematics and computer science from the University of Adelaide and a doctorate in spacecraft mission design at the University of Stuttgart in Germany. At NASA Ames Research Center in 2009 Rogan became the chief systems architect for a fledgling nanosatellite program called PhoneSat which spun off a company called Planet Labs. After missing this Silicon Valley unicorn opportunity, Rogan spent three years at NASA Johnson Space Center in Houston coding flight software and statistical safety analysis tools for the Orion capsule. He then entered the USAF training pipeline to become a Rescue Combat Systems Officer flying the HC-130J Hercules. Flying rescue sorties after-hours and occasional civil rescue alerts, Rogan returned to California with the Defense Innovation Unit in the US Department of Defense, ultimately serving as the space portfolio's Chief Engineer. He managed projects from high specific energy batteries and universal docking adapters to radiation hardened microelectronics, culminating in the hybrid space architecture, an ambitious program to provide secure internet access to every satellite in orbit, managing federal contracts including Microsoft Azure, Google, AWS, Anduril and Palantir. Rogan is Adjunct Faculty at the non-profit International Space University, and was a founding staff member of ISU’s Southern Hemisphere Space Studies Program, and is a graduate of the USAF Test Pilot School's Space Test Course.
