Brian Liebel, PE | Director of Strategic Initiatives


Brian Liebel develops long-term educational, technical, and advocacy programming and implementation planning for the IDA. His objectives are to elevate the Five Principles of
Responsible Outdoor Lighting to be a central tenant for outdoor lighting design and to develop further collaborations with the lighting community to promote IDA’s objectives of reducing light pollution. Brian first started collaborating with the IDA through his previous position as the Director of Standards and Research at the Illuminating Engineering Society, working closely with the IDA to achieve the first IDA/IES MOU and the successful passage of the joint IDA/IES Five Principles of Responsible Outdoor Lighting. This partnership led to successfully integrating the IDA as an organizational member in IES technical committees, ensuring that IDA’s perspectives are represented in the IES standards development process.

Throughout his 35-year career, Brian has dedicated his efforts to balancing the human need for light with environmental concerns, and always with a reliance on solid science. His career in lighting started with the University of Kansas Architectural Engineering program, after which he moved to the San Francisco Bay Area and became an established lighting designer, electrical engineer, lighting educator, and energy conservation advocate. Brian’s private consultation practice has kept him independent while receiving significant appointments, such as the Lighting Program Director at the Pacific Energy Center and the Principal Investigator for the U.S. Department of Energy in assessing the effects of light spectrum on vision. In his last position at the IES prior to joining the IDA, Brian was the chief architect in modernizing the IES’ standards development process and in expanding collaborations with international organizations.

Brian comes from a small town in the mountains of California, where he grew up gazing at the stars, unfettered by light pollution. To this day, he makes an annual trip from his home in Florida to backpack in the backcountry of the Sierra Nevada mountains to get his ‘fix.’

Savannah Pobre | Advocacy Intern


My name is Savannah Pobre and I am a senior at Princeton University majoring in Astrophysics and minoring in the History and Practice of Diplomacy with an expected graduation date in May of this year. During my undergraduate career, I’ve had the opportunity to engage in a range of independent research projects in which I have pursued astrophysics research in topics such as Brightest Cluster Galaxies and protoplanetary disks both at Princeton and internationally with organizations like the European Space Observatory and Atacama Large Millimeter Array (ALMA). Alongside these projects, I have partnered with the Princeton Sociology Department and the School of Public and International Affairs to conduct research on Diversity, Equity, and Inclusion efforts for planetary and space scientists as well as space policy and space law for cislunar space and space debris mitigation efforts. Off campus, I am a new member of the Committee to Protect Astronomy and the Space Environment (COMPASSE) AAS committee and am looking forward to starting my Master’s Degree in Space Studies from the International Space University (ISU) program this upcoming fall. I am excited to work as an IDA Advocacy Fellow this year and continue to reach my goal of becoming an asset to the scientific research community both as a researcher in the field and as a voice to policy makers in areas such as space debris mitigation, space sustainability efforts, and dark sky awareness.
