Member of the Sleep Lab

Contact Prof Helen L. Ball


Helen Ball is Professor of Anthropology and Director of the University's Parent-Infant Sleep Lab . She pioneers the study of infant sleep and the parent-infant sleep relationship from a biosocial perspective. She obtained her PhD in Anthropology from the University of Massachusetts, Amherst in 1992. Broadly defined, her research examines sleep ecology, particularly of infants, young children and their parents. This encompasses attitudes and practices regarding infant sleep, behavioural and physiological monitoring of infants and their parents during sleep, infant sleep development, and the discordance between cultural sleep preferences and biological sleep needs. She has conducted research in hospitals and the community, and contributes to national and international policy and practice guidelines on infant care. She pioneers the translation of academic research on infant sleep into evidence for use by parents and healthcare staff via ISIS -- the Infant Sleep Information Source website ( In 2013 Prof Ball received an award for Outstanding Impact in Society from the Economic and Social Research Council for her work on parent-infant sleep.

Queen's Anniversary Prize

Their Royal Highnesses The Prince of Wales and Duchess of Cornwall have presented the UK’s highest academic honour to Durham University for research that has helped to shape the way babies sleep and how parents care for them at night time.

At the awards ceremony at Buckingham Palace, similar to an investiture, the Royal couple awarded The Queen’s Anniversary Prize for Higher and Further Education to the University’s Vice-Chancellor, Professor Stuart Corbridge, and Professor Helen Ball, Director of the Parent-Infant Sleep Lab, with the University’s Chancellor, Sir Thomas Allen, in attendance.

The prize has been awarded to Durham University for ‘leading influential research on parent-infant sleep with a widely-used public information service’. The awards, part of the national honours system in the UK, are approved by The Queen on the advice of the Prime Minister from recommendations made by the Royal Anniversary Trust’s Awards Council.

The University’s Vice-Chancellor, Professor Stuart Corbridge, commented: “We are hugely honoured to receive this prestigious award, which recognises the immensely valuable and wide-reaching impact of the research carried out by the team in the Parent-Infant Sleep Lab. At Durham, we aim to deliver research that is world-leading and world-changing and the work of the Parent-Infant Sleep Lab is a perfect example of this commitment.”

Dr Charlotte Russell, BA, PhD

Sleep Lab Manager & Impact Evidence Manager in the Department of Anthropology
Postdoctoral Research Associate in the Sleep Lab

Contact Dr Charlotte Russell

Charlotte's research interests focus on the practical and theoretical application of evolutionary medicine to issues relating to childbirth and childhood, with special focus on the consequences of parent-infant separation. She also works on the translation of research evidence for public consumption, its role in influencing public behaviour, and in effecting change in policy and practice. 


Charlotte received her PhD in Anthropology from the University of Durham in 2007, following a BA in Human Sciences in 2001. Her doctoral thesis focused on a craniometric analysis of British and Danish archaeological populations, while her undergraduate dissertation addressed issues relating to the use and knowledge of traditional (folk) and complementary medicines in a North Yorkshire village.

Charlotte joined the Durham University Parent-Infant Sleep Lab (now DISC - the Durham Infancy & Sleep Centre) in 2007 as NECOT (North-East Cot Trial) project manager. In 2011 Charlotte and Professor Helen Ball obtained ESRC follow-on funding to set up the Infant Sleep Information Source (ISIS) website, now known as Basis - the Baby Sleep Info Source. This website provides a means by which up-to-date, evidence-based information about infant sleep can be disseminated to parents and health-care professionals. We also have also developed an app to complement the website; educational materials; contribute widely to national and international policy development; and provide training sessions for HCPs and volunteers working with parents.

Charlotte currently holds a full-time research position in the Department of Anthropology, managing DISC; supervising student projects and lab staff; and pursuing her own research which complements the Centre's core themes of investigation.

Dr Catherine Taylor, BSc, MA, PhD

Research Associate in the Department of Anthropology

In 2007 Catherine graduated from Durham University with a BSc in Medical Anthropology (Health and Human Sciences). Catherine was awarded an ESRC/MRC 1+3 postgraduate studentship and continued to study at Durham completing an MA in Research Methods in Anthropology in 2008 and a PhD in Medical Anthropology in 2014. During her postgraduate study she was supervised by Prof. Helen Ball and became a member of the Parent-Infant Sleep Lab ( Catherine’s PhD research was a qualitative follow-up of a large randomised trial known as the North-East Cot Trial (NECOT) which investigated the impact of cot type (stand-alone v’s side-car crib) on breastfeeding outcomes among mother-infant dyads in North-East England.

Since completing her PhD, Catherine has continued to work with the Parent-Infant Sleep Lab team on projects including the Risk and Reality Project exploring the effects of infant safe sleep education on parental bedsharing behavior, infant nighttime care and understanding of Sudden Infant Death Syndrome (SIDS) risk factors. She was the project manager for the Let’s talk About Sleep! Project (Fife, Scotland), a collaborative project between Durham University Parent-Infant Sleep Lab, University of Bristol School of Social and Community Medicine, The Scottish Government, Scottish Cot Death Trust and NHS Fife.

Catherine now manages the ESRC IAA-funded Coping with Infant Sleep project which is a collaboration between the Durham University Sleep Lab, Possums Clinic in Brisbane Australia, and the Great North Children's Hospital, Newcastle-upon-Tyne.

Ms Allison Dixley, BA, LLB, MA

PhD Student in the Department of Anthropology

A mother and former nursery nurse, Allison has two first-class degrees in Early Childhood Studies and Law. She obtained a Masters in Research Methods with Distinction at Durham, and is now in her second year of a collaborative ESRC-funded PhD studentship supported by UNICEF Baby-friendly Initiative and supervised by Prof. Helen Ball and Dr Charlotte Russell. Allison is the principle investigator for the Swaddle Sleep Study, a lab-based investigation into the effects of swaddling on infant sleep, feeding and behaviour. She has devised an innovative technique for assessing swaddle tightness, and is working with an electrical engineer to produce a calibrated pressure sensor.

Allison has written for numerous publications including Practical Preschool, Early Years Educator and Nursery Education. She is the author of Breast Intentions (Pinter and Martin Press 2014) a monograph drawing on academic research in anthropology, psychology, biology, and philosophy to shed light on the hidden emotions of early motherhood.
