In my PhD-project I use a rat model to simulate shift work. I investigate how shift work affects the circadian rhythm, metabolism and the brain.
Shift work is associated with mulitple negative health outcomes such as disrupted waking function, sleep disturbances and metabolic problems. I aim to find explanations of why and how these problems arise.
