Brief description of PhD project

My PhD project is part of the ENLIGHT project. The overall aim of the ENLIGHT project is to explore new and optimal light conditions to improve cognition, mood, and health in people with mild dementia. My focus is on the acute effects of daytime light exposure on attention in healthy, young adults. Reserarch method: laboratory experiments in the Human Light Lab.
