Catrin holds an MMath degree and an MSc in Computer Systems from the University of Wales, Bangor, and completed her PhD on classification methods for fMRI data in 2011. Catrin joined the Centre for Health Economics and Medicines Evaluation in 2010. Catrin has since worked on multiple health economic modelling projects and trial-based economic evaluations and has supervised post-graduate health economic students in the fields of orphan drugs and pharmacogenetics. Her research interests lie in the methodologies of trial-based economic evaluation and decision analytic modelling.  

Her research has led to over 30 publications including in the prestigious medical journals The Lancet and BMJ, as well as the top-ranking discipline-specific journals, Clinical Pharmacology and Therapeutics, Value in Health, and Health Economics. She is currently the alternate member (deputy) Health Economist for the New Medicines Group in Wales. 

Catrin leads and supports the health economics components of several projects aligned with her interests.

• Public engagement in health economics: Science Village in the National Eisteddfod of Llŷn and Eifionydd.

  Public engagement in health economics took place at the Science Village during the 2023 National Eisteddfod in Wales, where staff and students of CHEME hosted an interactive stall engaging visitors of all ages. Activities included a card game exploring NHS costs and a creative exercise on measuring health and comparing healthcare interventions. These activities introduced key economic concepts such as opportunity cost and cost-effectiveness while gathering public insights. Designed and delivered by researchers with varying Welsh language proficiency, the sessions attracted up to 150 participants per day, enhancing public engagement with health economics.

• BU-IIA Funded Project: VOICES-DDH: Value of information and cost-effectiveness of screening for developmental dysplasia of the hip (DDH)

  Uncorrected DDH is associated with long-term morbidities including chronic pain and arthritis. When identified early, DDH can be treated with non-surgical interventions, believed to prevent long term limitations. Determining the optimum DDH screening strategy in terms of both clinical- and cost-effectiveness has been identified as a top ten research priority for clinical effectiveness in children’s orthopaedics in the UK, and as a research priority by a James Lind Alliance Priority Setting Partnership. Based on a value of information analysis the proposed work will identify research priority areas within the DDH pathway and also generate evidence which will be included in future research proposals in DDH. Additionally, the results will provide evidence linking costs and efficacy for service managers and industry which can aid development and implementation of new screening programmes and technologies.
