Paul A. Boley, PhD

Paul is an Associate Researcher at the Max Planck Institute for Astronomy in Heidelberg, Germany. He worked as a programmer on light pollution modeling software from 2003–2007, developing programs to predict night-sky brightness for Coconino and Pima counties in Arizona. Paul received his PhD in Astronomy and Astrophysics from Heidelberg University.

Christian B. Luginbuhl

Chris is an astronomer specializing in the quantification and modeling of the effects of outdoor artificial lighting on the night sky, and lighting codes and their effect on controlling sky glow. He has been involved in light pollution control efforts since 1986, and was a principal author of the innovative 1989 Flagstaff and Coconino County (AZ) outdoor lighting codes, as well as the IDA Outdoor Lighting Code Handbook and Pattern Code. He has assisted over two dozen communities with development of outdoor lighting codes.

Benjamin R. Luginbuhl, PhD

Ben is a materials scientist and software engineer, specializing in creating custom applications for data collection, processing, and presentation. He serves as a board member for the Flagstaff Dark Skies Coalition, where he volunteers his time to spread awareness on light pollution and its impact on night skies. He received his PhD in Materials Chemistry from the University of California, Santa Barbara.

Donald R. Davis, PhD

Don is a planetary astronomer, working primarily in the field of small body evolution and dynamics. He has been actively involved in light pollution educational and control efforts since 1986, serving as president of the International Dark-Sky Association (IDA) Board of Directors (1997–2005), and sitting on the Pima County Outdoor Lighting Committee (1986–2005; chair 1994–1998). He has been involved with the quantitative measurement of skyglow since the pioneering study done at Organ Pipe National Monument (1995).
