Our research focuses on the promotion of mental and physical health across the lifespan. We use randomized controlled studies to test the causal impact of behavioural, cognitive, and emotional interventions. We also study bio-psycho-social mechanisms of action with a focus on brain functions and connectivity, emotions, as well as interpersonal and intergroup behaviour. Furthermore, we use prospective cohort studies to examine epigenetic and cell mechanical alterations associated with work-related stress and depressive symptoms.
