LUCI Talks

Virginie-GABEL

Virginie Gabel, Founder and CEO of Clock&me; Board Member of Good Light Group

Virginie Gabel is a chronobiologist and sleep scientist. She obtained her PhD at the University of Basel, Switzerland and did her post-doctoral research at the University of Stanford, USA. During that time, she studied how light and aging impact human behavior, cognitive performances, and sleep. Back in France, she is now studying human adaptation to various environments (desert, jungle, cave, Lapland etc.) and its effects on sleep and circadian rhythms.
Beside her research, she founded Clock&me, a consulting firm where she helps companies preventing risks linked to lack of sleep through trainings, conferences, seminars and consultancy. She is also a board member of the Good Light Group, an international non-profit organisation which advocates proper light exposure throughout the day. The main objective of the group is to promote the good use of artificial light and raise public awareness about the health benefits of natural light.

Christopher Kyba, Post-doctoral researcher at GFZ-Potsdam

Christopher Kyba is a physicist who has been studying light in the outdoor environment since 2009. He works with data from many different sources, ranging from satellite observations and aerial photos to all sky imagery and observations with the human eye. He has led the development of a number of citizen science projects and tools, including Radiance Light Trends, the Loss of the Night app, My Sky at Night, and most recently the Nachtlichter (Night Lights) app. He served on the board of directors of the International Dark-Sky Association during 2012-2015, and co-founded the “Artificial Light at Night” conference series. In 2022, he was the recipient of the Leon Gaster Award from the Society of Light and Lighting for an innovative experiment involving satellite observations and dimmable LED street lights in Tucson, Arizona. Christopher lives in Bochum, Germany, with his wife, two children, and one very old cat.
