Dr Dan Denis was an undergraduate and MRes student at Goldsmiths, University of London, where he developed an interest in unusual sleep phenomenon such as sleep paralysis in collaboration with Chris French and Alice Gregory. He went on to get his PhD in Psychology with Richard Rowe and Elizabeth Milne at the university of Sheffield, before accepting a postdoc position at King’s College London, supervised by Alice Gregory. This work focused developing a clinical trial to evaluate predictors of treatment outcome for cognitive behavior therapy for insomnia. He is now a postdoc at Harvard Medical School, working in the lab of Robert Stickgold researching the role sleep plays in the consolidation of memories in health and disease. He is particularly interested in how the brain prioritises which information that is learnt throughout the day is consolidated during subsequent sleep.
