Professor Carrie Llewellyn is a Professor of 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. 

In 2019 she was appointed as Chair of the South East and Central (SEC) Regional Advisory Committee for the NIHR Research for Patient Benefit Programme.  

Carrie has taught undergraduate medical students since 2002 and has twenty years’ expertise in applied, patient orientated research across a range of research designs and analysis: both quantitative (interventional RCTs, cluster RCTs, prospective cohort studies, discrete choice experiments) and qualitative methods and leads a portfolio of applied behavioural research in sexual health, related mainly to sexually transmitted infections (STIs) and HIV prevention, in addition to research furthering our understanding of patient’s preferences for health services.

Carrie sits on the management board for the Centre for Transforming Sexuality and Gender at the University of Brighton and the Centre for Cultures of Reproduction, Technologies and Health (CORTH) at University of Sussex. She has previously been a member of the British Psychological Society’s (BPS) Research Board.She is lead editor of the 3rd edition of the Cambridge Handbook of Psychology, Health and Medicine (Cambridge University Press) published in 2019.

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) and Deputy Chair of the Postgraduate Medical Education Unit Area Exam Board (BSMS).


Reducing the burden of STIs including HIV is a public health priority in the UK and people from ethnic minority groups, such as Black, Asian and minority ethnic (BAME), are disproportionately affected by sexually transmitted infections (STIs)/HIV and experience challenges accessing sexual health services due to discrimination and stigma. Alongside colleagues at the University of Westminster, University of Southampton and Positive East, Carrie is currently collaborating on The AUDITED Project (see link below) funded by NHS/The Health Foundation/NIHR. Home-based and online STI/HIV screening services are increasingly used within the NHS, yet they fail to take into account the cultural distinctiveness of minority groups and the difficulties they face. This results in lower screening uptake and lower use of clinical interventions and therefore contributes to enduring health inequalities. In partnership with community-based organisations, our team has designed and piloted an automated chatbot, called Pat, to improve knowledge of STIs/HIV and promote online screening services.

Carrie is co-investigator on a number of other sexual health projects funded by the NIHR with colleagues across the UK. She has a number of students undertaking research in the field of sexual health and also has a particular interest in the broader health inequities experienced by those identifying as LGBTQi. 

With an international editorship, Carrie has recently led on the 3rd edition of the Cambridge Handbook of Psychology, Health and Medicine: Editors: C Llewellyn, S Ayers, C McManus, S Newman, T Revenson, K Petrie, J Weinman. Published by Cambridge University Press: Cambridge.
