Ruskin Hartley | Executive Director


Ruskin Hartley joined the International Dark-Sky Association as its executive director in 2019. Ruskin brings more than 20 years of conservation experience to guide IDA’s work to protect the night sky.

Ruskin has spent his career directing and managing conservation programs that protect the nation’s land, water, and ocean resources–from primeval forests to the iconic beaches of Southern California. He served as executive director of Save the Redwoods League, a non-profit dedicated to protecting and restoring the redwood forest. He also served as the president and CEO of Heal the Bay in Los Angeles, and as vice president of resource development at Fair Trade USA, an award-winning social enterprise seeking to alleviate poverty around the world. Ruskin has experience leading public-private partnerships and scientific collaborations, including his work to launch the Redwoods and Climate Change Initiative. He has seen firsthand that people are moved to protect places that inspire them and looks forward to bringing that energy to the beauty of the natural night-time sky.

Originally from the United Kingdom, Ruskin holds a bachelor’s degree from the University of Cambridge and a master’s degree from the University of East Anglia. When not working, Ruskin loves to head out on the trail with his wife and kids or cookout under the stars.


Susan Ciarniello | Administrative Director


Susan has worked for IDA since 2004. The longest-serving current employee, she has enjoyed seeing the tremendous change in public awareness of the issues regarding light pollution. As membership director, Susan organizes the IDA database and deals directly with IDA members. Most anyone who calls during business hours will hear Susan’s pleasant voice on the telephone. Members and volunteers often remark on Susan’s competence and polite demeanor. Her broad business background, encompassing sales, purchasing, and administration helps Susan slowly but surely increase IDA’s member base. In an effort to expand IDA’s sphere of influence, she has started to restructure membership retention efforts and initiated several successful campaign drives. In addition to managing our active membership system, Susan has recently taken on the role of office manager. Her bachelor’s degree in business administration from George Washington University has helped her initiate changes in IDA’s accounting system to expedite the public posting of public financial records, which has benefited donors and financial administrators.


Bettymaya Foott | Director of Engagement


Bettymaya Foott grew up in picturesque Moab, Utah. Spending summer nights sleeping on the family trampoline under the stars, she fostered an early appreciation for the night sky. Her childhood was filled with hiking, camping, boating, and wandering in the desert, both below the hot sun and under clear dark skies. She graduated from the University of Utah Honors Program with an H.B.S. in Environmental and Sustainability Studies and a Minor in Spanish Language and wrote a thesis entitled “Light pollution hazards within ecosystems and mitigation strategies for the future.” Her dark sky career began with working for Utah State Parks as a Dark Sky Intern and then seasonal employee, starting 12 International Dark-Sky Park Applications across the state. She then worked as Coordinator for the Colorado Plateau Dark Sky Cooperative and the Consortium for Dark Sky Studies at the University of Utah. Now, she is incredibly excited to join the team at IDA as Director of Engagement. When off the clock, Foott loves to practice night sky photography. Preserving dark skies is her life goal and she is incredibly excited to continue this journey of saving the stars!


Annamarie Schaecher | Development Associate


Annamarie has engaged with the Tucson community in a number of conservation-based efforts. During her work as a School Program Coordinator at the Arizona State Museum in the early 2000s, she taught elementary school students about Tucson’s cultural heritage. She later worked at Sky Island Alliance to provide education and outreach for an effort to secure Wilderness designation for the Tumacacori Highlands south of Tucson. Annamarie combined her interests in education and the environment into a Master’s thesis from the University of Arizona about the implication for place-based education for Mexican American students. After teaching humanities in a Tucson middle school for several years, Annamarie returned to museum education and later provided educational outreach for the Cienega Watershed Partnership.  Annamarie’s role at IDA is to support and contribute to the numerous projects underway to connect people to the night sky.


Pete Strasser | Technical Director


An astral photographer since age five, Pete Strasser has long been interested in the practical and aesthetic effects of light. His degree in plant pathology from the University of California, Davis, imparted detailed insight in the composition and effects of different light sources. This knowledge proved invaluable during his work as IDA’s Technical Advisor and then Technical Director from 2006-2011. After a five-year hiatus, Pete returned to his position in 2016 as the IDA Technical Director. In this role, Pete oversees the IDA Fixture Seal of Approval program, which certifies compliant lighting products as “dark sky friendly,” and educates the public and the lighting industry about smart lighting choices. Pete served on the Illuminating Engineering Society of North American (IESNA) – IDA joint Model Lighting Ordinance task force, for which he received the IESNA President’s Award. Currently, Pete serves on the IESNA Research Committee and is chairman of the International Commission on Illumination Technical Committee on the Effects of Artificial Light and the Natural Environment. He has also worked closely with the U.S. Department of Energy and Environmental Protection Agency to establish criteria for their EnergyStar programs relating to Outdoor Solid State Lighting (SSL). Pete’s technical expertise in SSL technologies has helped many individuals and institutions promote and implement efficient, appropriate, and effective lighting practices.

Ashley Wilson | Director of Conservation

Ashley is a Tucson native and has always been enamored with the natural environment and its dark skies. Ashley’s passion for encouraging people to learn and care about the world around them led her to pursue an undergraduate degree in Ecology and Evolutionary Biology with Honors from the University of Arizona and later a master’s degree in Biological Sciences concentrating in Sensory Ecology from California Polytechnic State University. During this time, Ashley provided multiple town hall presentations to educate citizens on how their use of lighting can impact the nighttime environment, nocturnal animals, as well as their own health. She also participated in the National Park Service’s Future Park Leaders of Emerging Change internship program where she created the International Dark Sky Park application for Voyageurs National Park. Afterward, she moved to Florida to work as a lighting project specialist for Sea Turtle Conservancy, where she helped beachfront properties retrofit their exterior lights to be sea turtle-friendly. To increase her knowledge on lighting retrofit projects, Ashley also completed her LS-I lighting specialist certification through the National Association of Innovative Lighting Distributors. Today, Ashley is ecstatic to work with IDA as the International Dark Sky Program Manager, where she collaborates with advocates and volunteers to help them promote effective uses of outdoor lighting and protect pristine dark skies around the world.
