Regional Visibility Poster

Helen Ball obtained her PhD in Biological Anthropology at the University of Massachusetts, Amherst in 1992. Her undergraduate degree was in Human Biology, and her interests span both biology and anthropology. Helen spent several years in the Caribbean where she conducted her PhD fieldwork. Following her appointment as a Lecturer in Anthropology at Durham in 1993 Helen began a programme of research on night-time infant care, established the Parent-Infant Sleep Lab in 2000, and was promoted to Professor of Anthropology in 2007. 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. See 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 (

Dr Charlotte Russell, BA, PhD

Research Associate 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 focusses 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.

Having spent 3 months working as a research assistant in the Sleep Lab in the summer of 2001, Charlotte returned 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. 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 policy development; and provide training sessions for HCPs and volunteers working with parents.

Charlotte now holds a full-time research position in the Department of Anthropology, running ISIS and overseeing Sleep Lab projects; supervising student projects and lab staff; and pursuing her own lines of research which complement the Sleep Lab's core themes of investigation.

Ms Cassandra Yuill, BA, MSc

Research Associate in Anthropology

Cassandra completed her undergraduate degree in Cultural Anthropology at the University of Maryland and received her MSc in Medical Anthropology from Durham University in 2013. Her Master's thesis focused on the nutritional and physical activity knowledge and behaviour of secondary school students in County Durham. She joined the Parent-Infant Sleep Lab in late 2013 as a part-time Research Assistant before becoming a full-time staff member in 2015.

Since joining the Sleep Lab Team, Cassandra has worked on a number of projects operated out of the lab, particularly Let's Talk About Sleep!, which she project manages. She also assists in the management of the Infant Sleep Information Source, helping to launch the Co-sleeping Image Archive, and runs the infant sleep training workshops with Prof Ball and Dr Russell.

Dr Alanna E.F. Rudzik, BA (Hons), MSc, PhD


Alanna obtained her PhD in Anthropology from the University of Massachusetts Amherst in 2010 (Prof. Lynnette Sievert, Chair).  Her doctoral research with women from São Paulo, Brazil, focused on the effects of stressful life circumstances on breastfeeding duration in the early post-partum period, employing both biological and ethnographic research methods. Alanna was awarded a doctoral fellowship from the Canadian Social Sciences and Humanities Research Council (SSHRC) to fund her PhD research. Before coming to Durham, she held a SSHRC post-doctoral fellowship at the University of Toronto, working with Prof. Daniel Sellen, in which she investigated cultural norms of infant feeding and mothering among Torontonian women. Alanna joined the Parent/Infant Sleep Lab in January 2012 upon being awarded a Durham University International Junior Research Fellowship.  Her current research focuses on the influence of breast- versus formula feeding on the development of sleeping patterns in infants through the first year of life. Other research interests include women's experiences of breastfeeding, determinants of breastfeeding duration, food security and maternal mental health, and biomarkers of stress.

Ms Catherine Taylor 

PhD Candidate in Anthropology 

Catherine graduated from Durham University with a BSc in Human Sciences (medical anthropology) in 2007 and was awarded 1+3 postgraduate studentship funding from the ESRC/MRC.   Catherine continued to study at Durham University and graduated in 2008 with an MA in Research Methods in Anthropology and is currently in the final year of her PhD program. 

As a postgraduate student Catherine has worked as a research assistant on the North East Cot Trial (NECOT) and her PhD research is a qualitative follow-up investigation of NECOT involving mothers who participated in the study and NHS postnatal ward staff.

In 2010 Catherine secured funding to complete a 3 month internship at the charity Diabetes UK and in 2011 she was awarded additional ESRC funding to spend 2 months visiting the University of North Carolina, USA.  During this trip she was under the supervision of Professor Miriam Labbok director of the Carolina Global Breastfeeding Institute (CGBI) and also spent time at Duke University alongside postdoctoral fellow Dr Kristin Klingaman, a previous supervisee of Professor Helen Ball at Durham University.

Ms Denise Crane, MA, BSc

PhD Candidate in Anthropology

Denise entered higher education as a mature student in 2004 completing the Foundation Programme based at Durham University Queen's Campus. Denise progressed onto her degree at Durham University and graduated  in 2008 with a BSc in Human Sciences (Biological Anthropology). In 2008 Denise received a 1+3 MRC/ESRC Interdisciplinary Studentship award  and in September 2009 completed her MA in Anthropological Research Methods. Denise is currently undertaking her PhD on the BradICS project which is researching  infant care practices and unexpected infant death in the multi-cultural urban population of Bradford.

PhD in Anthropology completed Nov 2011

Dr Lane Volpe, BA, MA, PhD

Honorary Research Fellow, Medical Anthropology

Lane received her PhD in Anthropology from the University of Durham in 2010, working with supervisor Professor Helen Ball in the Parent-Infant Sleep Lab. She previously served as the Project Director of the Mother-Baby Behavioral Sleep Lab at the University of Notre Dame in South Bend, Indiana, USA. As Project Director, Lane directed part of an interdisciplinary research project entitled "Predicting and Preventing Child Neglect in Teen Mothers" with Principal Investigators Dr. John Borkowski and Dr. James McKenna. Having trained and worked at the only two anthropology-based behavioural infant sleep labs in the world, she is well-versed in the theories and contemporary research findings surrounding infant sleep, including such topics as breastfeeding, bedsharing, SIDS, nighttime parenting, and public health policy. Lane's doctoral thesis examines the nighttime parenting styles of adolescent and adult first-time mothers and their 4-month old infants. Her research also explores how mothers receive and apply medical and public health recommendations, and how their personal experiences affect the decisions they make regarding infant care. She previously completed both her Bachelor of Arts magna cum laude (1998) and Master of Arts (2002) degrees in Anthropology at the University of Colorado, in Boulder, Colorado, USA. Lane has been a Durham Doctoral Fellow, a member of the Medical Anthropology Research Group, and has tutored for the Medicine in the Community module, a component of undergraduate education in the School of Medicine and Health at Durham University.
