Dr Dietmar Hager (AT)
Stargazer Observatory

Dr Dietmar Hager

Dr Dietmar Hager is an astrophotographer and hand surgeon. His fascination with stars began in childhood, spending hours at the Kepler Observatory in Linz and conducting guided tours by age 16. Today, he shares his passion through shows at the Ars Electronica Center in Linz and other events. Inspired by his father's precision engineering and Leonardo da Vinci's anatomical drawings, Dr. Hager became a specialist in trauma and hand surgery, leading international courses. His medical precision enhances his astrophotography, creating captivating presentations. Dr. Hager also addresses light pollution's impact on nature and health, offering specialized lectures on the topic. Accordingly, his topic will also be about dark sky and light pollution.



Prof George C. Brainard (USA)
Director in the Light Research Program, Professor of Neurology and Neuroscience in the Thomas Jefferson University

Prof George C. Brainard

Dr Brainard's academic work has been concerned with the effects of light on biological and behavioral responses of animals and humans for more than forty years.  He has authored 130 original research articles and over 50 book chapters. He has written/edited 14 books or monographs including seven documents or standards for the International Commission on Illumination (CIE) and the Illuminating Engineering Society (IES).

Dr Brainard has been the US Division Six Director (USNC/CIE) since 1992, chaired the IES Photobiology Committee for ten years, and is currently co-chair of the IES Light and Health Committee. Recently, he was named as an IES Fellow in 2019 and subsequently was awarded the IES Medal in 2021. Among a number of other awards, he has been honored with the Johnson Space Center Director’s Innovation Award (2015), the Research Award from the Professional Lighting Design Convention (2013), and the Research Award for Excellence on Photobiology, Photochemistry and Photophysics, from the American Society for Photobiology (2010).

His presentation at the CIE Scientific Conference will focus on "Light and Human Health," exploring topics such as phototransduction, melanopsin, ipRGC, circadian rhythms, neuroendocrine and neurobehavioral effects, melatonin, human health, and implications for space flight.
