Research:

During my PhD, I study the effects of smartphone usage and the accompanying artificial light exposure during the evening on the human sleep-wake regulation. Thereby, I investigate how the emitted short-wavelength light from the smartphone affects sleepiness and alertness levels before bedtime and how it affects subsequent sleep along with its restorative functions, which can be examined in the next morning performance. An additional important question is also to which extent blue-light filtering software can diminish negative effects of the evening smartphone light-exposure and what other influencing factors should be considered in the future. In addition to behavioral indicators like reaction times and subjective rating score, I focus especially on electrophysiological measures (derived from EEG and PSG recordings) to draw further conclusions on the underlying brain activity.
