Marijke C.M. Gordijn, PhD, is guest researcher at the Chronobiology group of the University of Groningen, The Netherlands and founder/director of Chrono@Work B.V. After finishing her Masters in Biology, she did her PhD at the Psychiatric department of the University Medical Center in Groningen. Her main interest is translational research in the fields of chronobiology, sleep, light, metabolism and mood/well-being. Her goal is to use this knowledge to prevent the negative effects of chronobiological disruption in our 24/7 society. Marijke is vice-president of the Society for Light Treatment and Biological Rhythms, chair of the scientific committee of the Dutch Sleep Wake Society and co-founder of both Chronotherapy Network Netherlands and the Good Light Group.
