2022 Speakers

Annette Lee

IDA CEO & Executive DirectorRuskin HartleyU.S.

Global Conference Opening

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.

Diane Knutson Headshot

President, IDA Board of DirectorsDiane KnutsonU.S.

Global Conference Opening

Diane began to advocate for the reduction of light pollution by connecting policymakers with night preservation advocates within South Dakota, founding an International Dark Sky Chapter in South Dakota, U.S. The chapter coordinates events in the Black Hills (Paha Sapa), such as the Mickelson Star Trail nights and city-wide dark sky festivals. Diane earned a Master’s Degree from the University of Iowa, and a Bachelor’s Degree in Community Health Education from the University of Nebraska. As a business owner of night-friendly businesses and an involved parent, Diane brings business and leadership experience. Although she has two post-secondary degrees, Diane still believes some of her best education still comes from connecting with others under a sky full of stars. She finds Psalm 19 rings true,“….night after night they (heavens) reveal knowledge.” Diane wants all to remember that a portion of our time belongs under a star-filled sky, even if it’s simply to get a good night’s sleep.

Keynote SpeakerLisa Heschong, FIESU.S.

Day and Night, Life and Light

Lisa Heschong is a Fellow of the Illuminating Engineering Society (IES) and a proud member of the International Dark-Sky Association (IDA) local chapter in Santa Cruz, California. Trained both as an architect and ecologist, she has spent her career making connections between human experience and our built environment. After years of leading research on the energy performance of buildings, especially concerning lighting and daylighting design, she more recently turned her attention to how buildings impact our health and well-being. This talk will focus on how day and night are very different design conditions, yet they are two sides of the same coin intimately tied to our fundamental evolutionary physiology. Lisa will explore how healthier daytime environments influence healthier nights and vice versa.

Valerie Shrimplin Headshot

Valerie ShrimplinU.K.

Dark Skies and Light Pollution: An Art-Historical Approach

Valerie Shrimplin is Senior Research Associate at Gresham College London, having studied at the Universities of Bristol, Manchester, and the Witwatersrand (Johannesburg). She has lectured and published widely on the influence of astronomy and cosmology on art and architecture, particularly of the Byzantine, Medieval, and Renaissance periods.

Jairo VrolijkAruba

Light Pollution, why so mysterious? (Quantifying the knowledge on the ABC-islands)

Jairo Vrolijk is an electrical engineer, an avid astrophotographer, and as of 2018, the co-founder and current president of Space & Nature Aruba Foundation, an astronomy and general science organization on the island of Aruba. Aruba has become a large tourist haven in recent years, with an estimated 2 million people visiting yearly. About 50% of those tourists travel from large cities where light pollution is significant. Gazing into the night sky here in Aruba, they are amazed and in awe. Unfortunately, light pollution is still unknown within our community, and the value it can present is still not prioritized. This presentation will briefly illustrate some steps we, as advocates, have taken while gauging the knowledge about the topic within our community.

Myriam Patricia Lopez Yanez Headshot

Myriam Patricia Lopez YanezSaudi Arabia

How our Dark Sky Initiative has become a source for design creativity

Myriam Patricia Lopez Yanez was born in Ecuador and currently lives in the Kingdom of Saudi Arabia. She holds a graduate degree in Architecture from Ecuador and a Master’s Degree in Architectural Lighting Design from Germany. Myriam has completed her postgraduate studies becoming a Harvard Business School Alumni in 2022. She has practiced lighting design in Europe and the Middle East for over 17 years. She now holds the position of Lighting Design Director at the PIF’s The Red Sea Development Company and Amaala in KSA. The Red Sea Development Company has been applying Dark Sky Guidelines in big-scale Hospitality Development Projects, which has proven to be very challenging and rewarding at the same time. The lighting expectations and requirements of guests and operators must be constantly balanced with those of their wildlife. This can only be done with a strategic approach to lighting that considers the practical and functional side, with the environmental effects on sensitive species, and of course, the aesthetics and design. This talk will share the lessons learned and inspiring results of their design work.

Wiwat Changtrakul Headshot

Wiwat ChangtrakulThailand

How Thailand Got Their First National Dark Sky Sites

Wiwat Changtraku is an independent translator and ex-journalist based in Chaiyaphum province, Thailand. Since 2018, he began advocating for dark skies by building an online community, and by 2022 the first twelve national dark sky places were recognized, including three in his province. In this talk, Wiwat will share how after stumbling upon a potential dark sky site, he taught himself astrophotography and became an advocate for the protection of this site which coincided with a government astronomy organization’s initiative to do the same at the national level. Additionally, it will cover how Wiwat leveraged social media to help raise awareness about dark sky conservation.

Biraj Nainabasti Headshot

Biraj NainabastiNepal

Involving our Youth in Fighting for Darker Skies

Biraj is currently a high school senior. His love for astronomy and stargazing stemmed from when he went stargazing with relatives during his childhood in Nepal. However, he noticed that he couldn’t see the same constellations and sky that he could see in Nepal in the United States. After researching the topic and learning about IDA, he has been working hard on addressing light pollution by creating education outreach programs, writing articles, and researching the negative impacts of light pollution on our health. This talk will focus on involving the youth in the dark sky movement by showing the younger generations exactly what light pollution is and its negative consequences so they will continue in our footsteps in fighting this issue.

Rubaiat Rehman Khan Headshot
