I am the Deputy Director of Infection, Inflammation & Immunity Trials and Senior Research Fellow at the Centre for Trials Research.
I have recently been awarded a five-year post-doctoral research fellowship by Health and Care Research Wales to investigate the use of Pre-Exposure Prophylaxis (PrEP) in individuals at-risk of HIV-acquisition living in Wales.
My background is in Medical Statistics, and I have been working on the design, conduct, analysis, and reporting of randomised trials and other well designed studies since 2007. I completed my PhD at the end of 2016, with my thesis titled “Medication Adherence in Clinical Research and Associated Methodological Challenges”. As Deputy Director, I provide leadership to the Infection, Inflammation & Immunity division within the Centre for Trials Research.
Clinically, my research interests focus on prudent medication use in the field of infectious diseases, and my work can be broadly split into two key areas:
- Medication adherence – specifically, ways in which adherence to medication is conceptualised, measured, and modelled
- The development and evaluation of antimicrobial stewardship interventions
I am also actively involved in a large programme of research in the field of intellectual disabilities and other neurodevelopmental disorders.
My areas of methodological interest include:
- Trials and general research methodology (improving the ways in which we do randomised trials and other well designed studies)
- Causal modelling (modelling approaches that aim to answer causal questions, rather than purely associational)
- Missing data (prevention of, and fitting models when there are missing data).
Education and qualifications:
- 2013 - 2016: PhD "Medication Adherence in Clinical Research and Associated Methodological Challenges" (School of Medicine) Cardiff University, Cardiff, UK
- 2005 - 2009: BSc in Mathematics, Operational Research and Statistics (School of Mathematics) Cardiff University, Cardiff, UK (with placement year)

Teaching
- From the 2017/2018 academic year, I am lecturing on "Randomised Controlled Trials" as part of the ME 3092 Research Methods 1 module for Medical Intercalated BSc students
- In June 2016, I co-developed and delivered a three-day course on basic data analysis using the statistical programming language R (titled "learnR") to staff at the University of Namibia as part of the Phoenix Project (http://www.cardiff.ac.uk/phoenix-project)
- Previously, I have taught small and medium group sizes at both undergraduate and postgraduate level on topics including quantitative research methods, statistics, and critical appraisal
Supervision
- I am currently submitting proposals to supervise undergraduate and postgraduate students in the fields of medication adherence and infectious diseases
- I have supervised three undergraduate dissertations (2 x Medical Intercalated BSc and BSc Mathematics, Operational Research and Statistics) and two MSc dissertations (MSc Operational Research and Applied Statistics, MSc Bioinformatics and Biostatistics)
Since 2013, I have been awarded approximately £8m in grant funding, including approx. £400k as lead applicant.
