Research summary

I am primarily interested in off-line learning during sleep and wakefulness: my research investigates brain plasticity, focusing specifically on the changes in behaviour and neural activity which occur after initial learning. I’m particularly interested in changes occurring while a memory is not being encoded, practised, or recalled. These can happen both during sleep and during wakefulness.

Current interests in the lab fall into four main categories

  1. Consolidation of procedural skills
  2. Emotional episodes
  3. Transition of memories from episodic to semantic
  4. 'Sleep engineering’ or ways to manipulate sleep for greater cognitive and or health benefit (see TEDx talk)

Sleep is critical for both health and cognition. Our lab is developing ways to manipulate sleep (called 'Sleep Engineering’) in order to maximise its beneficial properties. We are working on ways to enhance memory, disarm negative emotions, and combat cognitive decline through ageing. Read more here.

Media activities

I am quite active in the media, and frequently give interviews for the BBC, NPR, and other networks. I recently gave a TEDx talk on Sleep Engineering, have written a popular book 'The Secret World of Sleep’  and edited a book of short stories about sleep 'Spindles’.
