Overview
I have over 20 years experience in soft tissue measurement, which has enabled me to develop and lead the successful Medical Experiment, Design + Computational Laboratory (MED+CL). We are expert generating new knowledge to understand, preserve and enhance soft tissue physiology and function. We use a combination of experimental methods and computational techniques to characterise soft tissue behaviour, both in vivo and in vitro.
We have a particular interest in inclusivity in sport, focussing on removing barriers and understanding risks. Our primary areas of research include the female athlete, and brain health. I also have a strong interest in research with potential clinical deliverables - especially orthopaedics, and in cardiac biomechanics, including a recently finished EPSRC-funded study investigating growth and remodelling, and have recently become involved in enhancing cancer-related diagnostics, by leveraging our recent EPSRC infrastructure investment to start developing new imaging phantoms.
Recent Work:
Fig 1. (a) Capturing heading kinematics, from Barnes-Wood et al., 2024. (b) Quantifynig the biaxial response of cardiac tissue, from Ahmad et al., 2023. (c) The hexahedral guide used to create a honeycomb helmet liner, from Adams et al., 2023. (d) Variation in Houndsfield unit achieved when adopting different 3D printing methods, from Lacan et al., 2023.
Industrial Collaboration:
My group and I actively engage with a breadth of industries and Standards committees (in the UK and US), national and international governing bodies. Our efforts focus on researching and developing novel technologies that can be translated into new products. We have worked extensively across the personal protection sector (e.g. Charles Owen, Champion Hats, Sports Labs, SPORTTAPE), creating many co-supervised, co-funded research roles that have been valuable in generating industry-specific knowledge and understanding. An example is the secondment of Finlay Taggart, developing our fundamental work (MacFarlane et al., 2024) to produce an on-pitch method of assessing skin injury risk.

Teaching
I teach a range of subjects that consider musculoskeletal biomechanics, and how the implementation of innovative design can add to this valuable area. These modules include:
- EN2451 - Biomechanics 1, focussing on the fundamentals of the musculoskeletal system.
- EN3450 - Biomechanics 2, considering the implementation of emerging technologies to design and manufacture patient-specific surgical guides.
- EN4119 - Ergonomics, introducing a novel intervention that can improve and/or protect musculoskeletal functionality, with efficacy tested on a participant population.
I supervise undergraduate and postgraduate individual projects, and am a Personal Tutor to undergraduate Medical Engineering students. I am also a Senior Fellow at Advanced HE (formerly the Higher Education Academy).
Biography
My research focusses on the interface of engineering and medicine. Alongside my team, we aim to identify new and novel solutions to reduce the risk of mortality, morbidity and injury, with a particular interest in application to sports and orthopaedics. Our research is of both a fundamental and applied nature, meaning we work with a range of academic, clinical and industrial collaborators within the UK and overseas. Internally, I hold memberships in both the High Value Manufacturing, and Medical Engineering, research groups.
My research team are primarily focussed on increasing inclusivity, or removing barriers to participation, in sport. We use our understanding of engineering and biology to better understand the anatomy and physiology of healthy and at-risk soft tisues, to then propose interventions that further enhance athlete participation. Under-represented populations, including the female and youth athlete, are special interests. We perform fundamental science, whilst engaging with policy makers and industry, to maximise the impact of our unique knowledge and expertise.
My research also includes a wider spectrum of engineering applied to medicine, meaning we work with a range of clinical colleagues and academic collaborators within the UK and overseas. I am active in orthopaedics - especially looking at how additive manufacturing can improve patient care. We have also worked investigating how the biomechancial behaviour of cardiac tissue changes with age, included the recently ended project funded by the Engineering & Physical Sciences Research Council, alongside the prestigious SoftMECH centre (University of Glasgow) and Swansea University.
My career started in 2003, graduating in Medical Engineering from the University of Bradford (1st Class (Hons)), at the time being one of very few universities to offer such a programme. I moved to Cardiff School of Engineering to read my PhD in soft tissue biomechanics, focusing on the tendo Achilles insertion site. I performed a series of biomechanical and anatomical analyses, revealing the complex interaction between adjacent tissues that ensures the interface can withstand such high loads. I was supervised by Professor Len Nokes (School of Engineering), the late Professor Mike Benjamin (School of Biosciences) and the late Professor Colin Dent (School of Medicine).
I am now a recognised expert in the Medical Engineering field and frequently review grants and papers, and examine students, across the UK and internationally.
