Chris is a Senior Lecturer in Exercise Physiology.

He graduated from the University of Glamorgan with a First class honours degree in Sport and Exercise Science. Following his graduation, he was awarded a prestigious JPR Williams Research Scholarship at the same institution, which allowed him to work towards an MPhil in Exercise Physiology. In 2012, Chris began working towards his PhD entitled “Cardiorespiratory fitness and its impact on cerebrovascular function: link to cognition”, which he completed in 2016. Chris had previously lectured at Cardiff Metropolitan University, where he contributed to the Exercise Physiology, as well as the Physical Activity, Health and Special Population modules.

Chris has facilitated the delivery of two multi-site, randomised control trials, which were funded by the National Institute of Social Care and Health Research Cymru and led by Cardiff University. The trials aim to assess the feasibility and potential functional benefits of physical activity (Engage-HD) and structured exercise training (ExeRT-HD) in patients diagnosed with the neurodegenerative condition Huntington’s disease.

Chris has also previously been the Stroke Research Coordinator for the Older People and Ageing Research Network Cymru (2011-2015), where he was responsible for facilitating new and developing existing innovative collaborations in stroke research in Wales.

Chris provided scientific support as part of “Project Everest Cynllun” – Richard Parks’ attempt to summit Mount. Everest without supplemental oxygen.


Current research interests:
1. Physical activity as a means of reducing stroke and neurodegenerative risk factors.
2. Factors that influence oxygen delivery to the brain.

Chris is currently a co-supervisor for 4 PhD students:
Mr Thomas Calverley – Exercise and Brain Health
