"I conduct research on the psychological and neural basis of altered and positive states of consciousness".
Main areas of research
The first line of my research focuses on studying the psychological and neural basis of altered states of consciousness utilizing the model system of the dreaming brain. I am especially interested in dream emotions and methodological issues in investigating dream (emotional) content.
The second line of my research explores the psychological and neural basis of (mental) well-being using a multidisciplinary and multilevel framework that draws on the concepts, theories and research from philosophy, psychology, neuroscience, and (molecular) biology.
I also investigate well-being across waking and dreaming states, that is, how waking well-being is related to dream (emotional) content.
