PhD student, Psychologist

“How does light influence human physiology, mental health and performance?” My main interests lie in the spectral composition of light, how it can be used (or not used) to enhance sleep, performance, and well-being and what we can do to live a healthy, sustainable lifestyle in a post-modern world.
