Dr Carrie Llewellyn is a Reader in Applied Behavioural Medicine, a behavioural scientist and a Chartered Psychologist and Associate Fellow of the British Psychological Society. She graduated King's College London with a PhD in Psychology as Applied to Medicine in 2005 and has since worked at BSMS.

She leads a portfolio of applied behavioural research in sexual health, related to sexually transmitted infections (STIs) and HIV prevention, in addition to research furthering our understanding of patient’s preferences for health services. Her current work is supported by grants from the National Institute for Health Research (NIHR).

In 2014 she was elected as Member of the British Psychological Society’s Research Board and between 2010 and 2014 she served as a South East Coast Regional Funding Committee Member for the NIHR Research for Patient Benefit Programme. She is an International Advisory Board member for the British Journal of Health Psychology.

Carrie has had a number of committee responsibilities at BSMS and the University of Sussex and is currently Chair of the Mitigating Circumstances Committee (BSMS), Deputy Chair of the Postgraduate Medical Education Unit Area Exam Board (BSMS) and member of the Honorary Titles and External Examiner Committee (BSMS).


Reducing the burden of STIs is a public health priority in the UK and there is international evidence that behavioural interventions can reduce the risk of contracting a new STI among sexual health clinic attendees. The applicability of this evidence to the UK setting is not clear and current practice across sexual health services in the UK is variable. Carrie is co-principal investigator with colleagues at UCL on a feasibility study funded by the HTA, which aims to develop and pilot a package of evidence-based sexual risk reduction interventions for those most at risk, which can be implemented in sexual health services.

Carrie is chief investigator of 'Project PEPSE' which is a multicentre RCT and economic evaluation of a psychological intervention to reduce risk behaviour amongst men who have sex with men (MSM) prescribed post-exposure prophylaxis for HIV following sexual exposure (PEPSE) also funded by the NIHR. This behaviour change intervention is informed by the Information-Motivation-Behavioral skills (IMB) model of health behaviour change and data are in analyses.

Carrie is co-investigator on a number of other sexual health projects funded by the NIHR with colleagues across the country. She currently has several PhD students in the field of sexual health and has a particular interest in public and professional views about HPV vaccination amongst males.

With colleagues across Universities in the south-east region, the NHS and working in this field of research in the community, Carrie aims to establish the South East Sexual Health Research Group, as part of new developments in sexual health research at BSMS.



Carrie contributes to the teaching of research methods on the 302 Scientific Basis of Medicine course. She supervises PhD students and module 404 (IRP) research projects.
