Honorary Professor

: Welsh speaking
: Available for postgraduate supervision

I am a medical physicist and registered clinical scientist; I worked in the National Health Service for over 40 years. In 2017, I retired as Head of Medical Physics and Clinical Engineering in the Cardiff and Vale University Health Board, based at the University Hospital of Wales. The responsibilities of the post included the provision of a wide range of clinical, scientific and technical services but my own areas of expertise were nuclear medicine, bone densitometry, body composition measurement and radiation safety. In 2021, I returned to work for the Health Board as a Consultant Clinical Scientist ito support the bone densitometry and osteoporosis services. I retired for a second time in 2023.

Throughout my career, I have had a strong interest in teaching, training and research. I am an Honorary Professor in the School of Engineering and I have co-supervised several PhD students whose projects have involved various aspects of medical radiation physics and engineering. In addition, I have acted as reviewer and internal examiner for Cardiff University research degrees.

Summary

Throughout my career, I have undertaken collaborative research and development with university academics and professional colleagues from a wide range of medical and surgical specialties.

This work has mainly involved the clinical application of physics and engineering in nuclear medicine, bone densitometry and body composition measurement. However, it has also included radiation safety and the evaluation of equipment and techniques. For an indication of the range of projects, please see the papers under the Publications tab, although a more comprehensive list appears in my ResearchGate profile.

My current research interests include optimisation in x-ray radiological imaging, standardisation of activity in radionuclide imaging, and identification and quantitation of radionuclidic impurities in radiopharmaceuticals and radioactive by-products in medical radioisotope production.
