I work as a consultant neurologist within the Department of Neurology and Sleep Disorders Centre at Guy's and St Thomas' Hospitals, and at London Bridge Hospital, the Cromwell Hospital. I am clinical lead for the Sleep Disorders Centre, Guy's Hospital, one of Europe's largest sleep units.
I am also Professor of Neurology and Sleep Medicine at the Institute of Psychiatry, Psychology and Neuroscience, King's College London.
I currently undertake general neurology clinics and specialist clinics for sleep disorders and epilepsy.
I completed medical school at Magdalen College, Oxford, and Imperial College at St Mary's. After general medical training, I went on to complete a PhD in the genetics of epilepsy and drug management at Imperial College London and the Wellcome Trust Sanger Institute, Cambridge.
I undertook neurological training at Guy's and St Thomas', Charing Cross Hospital and the National Hospital for Neurology and Neurosurgery, Queen Square.
After a fellowship in epilepsy and sleep medicine at St Thomas' and Queen Square, I joined Guy's and St Thomas' as a consultant in 2010.
I lecture regularly and have ongoing research interests in narcolepsy, epilepsy, sleepwalking, Kleine-Levin syndrome and restless legs syndrome. I have been or am currently principal investigator or collaborator in several multi-centre studies involving seizures, Alzheimer's disease, Parkinson's disease,narcolepsy, non-REM parasomnias, REM sleep behaviour disorder and insomnia.
I also have an interest in public education. I have presented two series on BBC Radio 4 and BBC World Service, on the brain and sleep - "Mysteries of Sleep", and "The Senses", on the neurology of our sensory world. I have also recently filmed "The Secrets of Sleep" for Channel 4 Television. My recent book "The Nocturnal Brain: Nightmares, Neuroscience and the Secret World of Sleep", published by Simon and Schuster, is out now. I am recipient of the 2019 Ellison-Cliffe Medal from the Royal Society of Medicine.
