Research interests

Off-line learning during sleep and wakefulness:

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

Current interests in the lab fall into three main categories:

  • consolidation of procedural skills
  • emotional episodes
  • semantic knowledge
