Biography
I am Professor of Behavioural Medicine at the University of Leicester and a primary care pharmacist. I lead a portfolio of research applying behavioural science to medicine-related challenges. I am experienced in delivering research spanning the full spectrum from diagnosing the nature of the problem through to designing targeted interventions and large-scale testing in definitive trials. My work includes both patient and practitioner behaviour change; two key strands are supporting deprescribing and medication adherence. Current research programmes that I am leading on these topics include:
- CHARMER which is a five year, £2.4M NIHR funded research programme to design and test a deprescribing intervention across 24 hospitals in England.
- IMAB-Qi which is a five year, £2.7M NIHR funded research programme to design and test a medication adherence intervention across 38 medical practices in England.
I am also passionate about research capacity building to secure the future of evidence-based healthcare. I am currently leading the NIHR incubator for pharmacy professionals which is three years of funding to build research capacity amongst the pharmacy profession.
My national/international roles include membership of the funding panels for NIHR Programme Grants for Applied Research and NIHR pre-application support fund, Pharmacy Research Advisory group and editorial boards for the journals Patient Preference and Adherence and International Journal of Pharmacy practice.
Below are links to some projects that form the core of my recent research:
Research Group or Lab Membership

Steven Watson (with Malcolm Adams) – Use of psychometrics to develop a self reported adherence questionnaire.
I joined the University of East Anglia in 2010 to complete a PhD entitled 'Development of a novel, validated tool for predicting patient adherence to prescribed medication'. As well as a particular interest in medication taking behaviour I have a more general interest in the roles of evolution, emotions, and somatic experience upon decision making. I am also interested in research synthesis and meta-analysis.
Before joining the UEA I gained my Psychology BSc (Hons) from Newcastle University in 2006. I then attained the degree of Master of Research in Psychology from Northumbria University in 2009, with a thesis entitled “The ‘halo effect’ as an evolved mechanism to promote short term mating with attractive partners”. Whilst at Northumbria I also conducted research into the effects of pre-natal androgen exposure on sexual dimorphism and aggression via differences in digit ratios.

Michael Twigg (with David Wright, James Desborough) - Development of community pharmacy services to support patient adherence to prescribed therapy with a particular focus on eczema and diabetes

Claire Easthall (with David Wright) – Development of community pharmacy services including domiciliary care to support patient adherence to prescribed therapy
I joined the Medicines Management Research Group as a PhD student in October 2010, having qualified as a pharmacist in July of the same year. I now continue to work as a locum community pharmacist whilst working on my PhD which is centred around the complex phenomenon of medication taking behaviours. My current research aims to explore and enhance patient medication behaviours by focusing on different aspects of non-adherent behaviour. Whilst a service evaluation of a domiciliary medicines support service will investigate interventions targeting unintentional non-adherence, a greater focus will be made upon the area of intentional non-adherence, where patients choose not to take their medication as prescribed. I am particularly interested in exploring and developing the use of cognitive based behavioural interventions as a means to altering patient behaviour and enhancing medication adherence and a large proportion of my PhD will centre around this. My research interests also lie with the evolving role of community pharmacists and the contribution to healthcare that can be made through their effective utilisation.
Prior to joining the Medicines Management Research Group, I had experience working in community pharmacy, initially as a pharmacy assistant and progressing to pre-registration pharmacist upon completion of my undergraduate masters degree in pharmacy, here at the UEA’s School of Pharmacy. I also have experience of working as a dispenser and medical receptionist in a GP’s surgery, where my passion for pharmacy and interest in medication adherence were first ignited.

Dr Estelle Payerne: Research Associate
I joined the medicines management research team in September 2011 as a Research Associate to develop an expertise in systematic reviews and meta analyses. I am currently working with colleagues on systematic reviews and meta analyses related to the predictors of medication adherence and effect of cognitive based techniques on medication adherence.
Prior to this I was already working in the school of Pharmacy but as a Senior Research Associate in Medicinal Chemistry. I was part of Prof M. Searcey’s group and was involved in several research projects focussing in the synthesis of peptides and small organic molecules with potential anti inflammatory and anti carcinogenic activities. I also undertook my PhD within the medicinal chemistry group working for Dr S. Matthews and my project was looking at the use of calix[4]arenes as scaffolds for new drug delivery systems.

Heidi Cate, PhD student (with Allan Clarke) – Developing and evaluating adherence interventions for patients with glaucoma.
I started my PhD with the Medicines Management Team (within the School of Pharmacy) in July 2011. My work centres around best practice and management of patients suffering with glaucoma. I have an interest in ways in which to improve patient adherence to medication, particularly with glaucoma patients. Before starting my PhD I was a Research Co-ordinator for the Glaucoma Research Unit at Norfolk & Norwich University Hospital Eye Department, carrying out clinical and surgical trials. I continue to manage the research team, during my period of study at the UEA.
Eman Hammad (with David Wright, John Wood) – An evaluation of the quality of information transfer between secondary and primary care and the extent of medicines reconciliation in primary care
Rowan Yemm (with David Wright, John Wood) – Estimation of the relative importance of information transferred at hospital discharge and evaluation of an electronic hospital discharge system.
Clare Aldus
I joined the School of Pharmacy in January 2012 as a Senior Research Associate to manage a Health Technology Assessment project to assess the effectiveness and cost effectiveness of multi-compartment medication devices. The project encompasses systematic review, focus groups, electronic medication event monitoring technology and a pilot study to test the effect of multi-compartment medication devices and requires close collaboration between researchers, students, health professionals and the public. I previously worked as a researcher at the Institute of Food Research (IFR), Norwich in the area of food safety microbiology with major focus on highly dangerous pathogens including Clostridium botulinum and verotoxigenic Escherichia coli. In addition to this I carried out work to support the mathematical modelling team in development of dynamic microbiological modelling programs and databases and have worked in collaboration with UEA on a Health Technology Assessment systematic review project. My main interest is the development and validation of methods and in addition to my work at IFR I was also a member of British and International Standards Organisation committees for the Microbiological Safety of Food and Animal Feed, carrying out work to develop and validate either traditional or molecular International Standard Methods for E. coli O157, Campylobacter jejuni and C. botulinum.
