Meet the SleepHubs Experts


Charlie Oulton


Having been a sleep sufferer for many years I really understand first hand how you can change your life by sleeping better, that’s why I created SleepHubs following advice from Sleep Experts. My journey made me realise what a difference could be made to many other sleep sufferers. Why wouldn’t I try and help as many people as possible sleep better – live better?

I am incredibly passionate about helping people with respiratory sleep disorders feel better as I really understand the importance of a good night’s sleep.

I qualified in medicine at Guy’s, King’s and St Thomas’ medical school in London.  Having completed my medical rotation and postgraduate training I specialised in respiratory physiology and sleep and ventilation medicine. I obtained a PhD from King’s College London in the investigation and management of ventilatory failure and continue my work in sleep and ventilation within the NHS, publishing journals and papers which I also present in person internationally.

I hope that I have changed the lives of many sleep sufferers by helping them understand the health benefits of getting a better nights sleep by identifying and treating their issues, allowing them to get quality sleep resulting in a more enjoyable life.

I have worked for the last 34 years in the field of occupational therapy and in 1999 I began to work with people with insomnia. I increasingly specialised in sleep and sleep problems, working with a team of leading sleep specialists, and seeing patients with the whole range of sleep disorders. To support this, I did specialised training – including short courses on sleep medicine and cognitive behaviour for insomnia and I regularly attend conferences and meetings on sleep. I have been involved in research and have written several articles on sleep as well as co-editing two books on sleep.

I now have a private practice specialising in insomnia,; I also do online work as a sleep coach and run training sessions for health professionals who want to help their patients who have sleep problems. 

I am a sleep expert offering therapy and consultant services with a Postgraduate Diploma in Sleep Medicine from Oxford University and an MSc in Health Psychology. I work with individuals experiencing insomnia and sleep problems using cognitive behavioural therapy for insomnia (CBT-i), and have experience in both the public and private sector.

I work with organisations and companies with an interest in sleep and wellbeing, delivering staff wellbeing talks and programmes, as well as writing articles for websites, newspapers and magazines.

I am a doctoral student at the University of Cambridge, researching Alzheimer’s Disease and sleep. My research combines molecular neuroscience research in fruit flies with extensive human data from the UK Biobank to elucidate the mechanisms of neurodegeneration.

My career goal is to develop better therapies to alleviate the consequences of neurodegenerative diseases.

Previously, I completed a BSc degree at Imperial College London in Biological Sciences. During my BSc, I founded and chaired the Sleep Society to raise awareness on the importance and science behind sleep (

At SleepHubs, I use my experience in sleep research and data science to further improve the services SleepHubs offers.
