John is a strategic leader and policy expert working at the forefront of environmental science and the emerging space economy. As the Executive Officer and Principal Consultant at Dark Sky Consulting, LLC, he transforms complex scientific data into actionable public policy and scalable organizational success.
Executive Leadership & Impact
John’s career is defined by his ability to bridge the gap between hard science and high-stakes operations. During his tenure as Director of Public Policy and Program Manager for DarkSky International, he engineered a 400% increase in organizational output by optimizing global certification workflows and leading critical regulatory initiatives. He is a recognized expert in the "New Space" sector, where he advises on the regulatory and environmental impacts of satellite constellations and orbital stewardship. As a co-founder of the Center for Space Environmentalism, John is currently building the future of space ethics and the protection of the night sky as a global commons.
Scientific Foundation & Technical Expertise
John leverages a rigorous technical background to solve complex, multi-stakeholder challenges. He earned a master’s degree in physics from Colorado State University and both a master’s and Ph.D. in astronomy from The University of Texas at Austin. Early in his career, he managed high-value technical operations at world-class facilities, including the Apache Point Observatory and the Sloan Digital Sky Survey. His contributions to science span fields from solar physics to galaxy evolution, providing him with a "full-stack" understanding of the technical requirements of modern research and infrastructure.
Global Influence & Service
A sought-after voice in international science policy, John holds leadership roles in several premier global organizations:
John is also an accomplished author of three books on the history of astronomy, including The Lost Constellations and Mystery of the Ashen Light of Venus. In recognition of his contributions to the field, the asteroid (14505) Barentine was named in his honor.
Beyond the Science
Beyond his professional advisory work, John remains an active amateur astronomer. This 'boots-on-the-ground' perspective informs his advocacy; he does not just analyze light pollution through satellite data, but through the eyepiece of a telescope. Whether curating lists of carbon stars or conducting visibility studies, his goal is to ensure that the technical precision required for science is matched by the policy rigor required to protect it.
