Sleep Well Science - Assessment and Remediation

Sleep Well Science is based at Nottingham Trent University’s (NTU) Department of Psychology. We provide customised, non-invasive at-home sleep and circadian functioning assessments.

This includes bespoke packages of science-led measures - from detailed consultation, through to measuring core body temperature, brain activity, blood oxygen concentration, hormone levels, wake-rest cycle and environmental monitoring, subjective sleep and fatigue.

All assessments include client-focused remediation support - under the guidance of leading sleep expert Professor John Groeger.

About us

Nottingham Trent University has a mission to be bold, do the right things and to change lives. As part of this approach, the Sleep Psychology team at NTU launched Sleep Well Science - a sleep assessment service for those requiring sleep support after suffering traumatic injury.

Sleep is fundamental to emotional, cognitive, and physical wellbeing. This is why we have developed a sleep assessment service to improve post-trauma lives. Our service offers a wide range of assessment techniques depending on the faced sleep challenge. On the basis of our scientific knowledge and practical insights, we will recommend assessments which reflect the needs of the individual, analyse the data, and critically assess any evidence of a problem.

From this, we will make informed recommendations to improve that individual’s sleep. Our service is based on state-of-the-art sleep understanding, and minimally invasive assessments in client’s own homes.


Our team

John Groeger is an internationally recognised sleep researcher, Chartered Psychologist, and Fellow of the British Psychological Society. He has been Professor of Psychology at Nottingham Trent University since 2017, and held full-time or visiting professor ships at Surrey, Monash, Cork and Hull. John has published two books and hundreds of scientific and professional papers about psychology, cognition, sleep and driving.

Kate Bosak graduated from Nottingham Trent University with a 1st Class Honours degree in BSc Psychology. Her interest in Sleep Psychology stemmed during her final year research project where she gained a 1st. For Kate’s project she investigated the correlation between chronotype and the post-lunch dip. This involved working with sleep assessment equipment like eCelsius and actigraphy, and analysing this sleep data.

Since graduating, Kate works as the Sleep Service Development Manager for Sleep Well Science. Kate has always wanted to help others, and is why she is so passionate about this approach to improve post-trauma lives.

Our Approach

After getting in contact with us, we will arrange an initial online consultation with Case Managers, clients, partners or other professionals as appropriate, in order to gain insight into the different perspectives on the client’s sleep challenges. We may later follow this up with on-line client/carer questionnaires which will allow us to place the sleep challenge it in a context appropriate to their age, sex and circumstances.

Depending on the sleep challenges identified, we will conduct one of two standard sleep assessments: a) measurement of the wake-rest cycle and sleep environment using actigraphy, and b) brain activity during sleep using EEG/ZMachine to identify more precise information about the client’s sleep structure, sleep stages and/or disorders.

Depending on the issues arising from the initial sleep investigations, there is scope to further identify remediation options by measuring (a) blood oxygen concentration using a Pulse Oximeter, (b) core body temperature using eCelsius, (c) sleep and circadian hormones using ELISA saliva/blood samples, (d) subjective sources of sleep loss and fatigue.

Upon return of equipment, we will analyse, report and interpret all sleep data and formulate personalised, scientific sleep improvement strategies. This formal report will then be discussed with the client, together with carers and/or appropriate professionals.

Our assessments

After getting in contact with us, all clients will undergo an initial consultation which involves an online interview with ourselves, the client and their partner or carer. This allows us to gain insight into the client’s sleep challenges, pre-trauma lifestyle, family/living circumstances. Following this, clients will complete some questionnaires for us to understand more about the client’s subjective sleep history
