Association between stress across life and changes in sleep and circadian rhythms, with a translational perspective (animal models and human studies).
I investigate different early life conditions and consequences for health later in life (sleep, circadian rhythms, behavior and cognition), and which factors can moderate the effects of adverse early life events.
Another research focus is on consequences of nightshift-work for sleep, circadian rhythms and waking function. One of the main goals is to investigate how different lighting conditions can be used to alleviate sleepiness and improve cognitive function during nightshift-work and to identify molecular mechanisms.
- Objective measures of sleep and waking function
- Objective measures of circadian rhythmicity
- Behavioural tests
- Subjective and objective measures of sleep and waking function
- Subjective and objective measures of circadian rhythmicity
- Cognitive tests
