    Biography

    I started my career in industry in instrumentation and control engineering, then moving into biomedical engineering after studying for a master’s degree in Bioengineering at Strathclyde University. In 1989 I joined the NHS / Northern Medical Physics and Clinical Engineering department based at Newcastle’s Freeman Hospital, first working with the Cardiovascular Physics and Engineering Research Group allied to Newcastle University, then becoming lead Clinical Scientist specialising in microvascular assessment i.e., studying the smaller blood vessels of the body. I have a PhD in the vascular optics pulse technique known as photoplethysmography (PPG), for which I am a recognised authority. I am a Chartered Engineer, Chartered Scientist, State Registered Clinical Scientist, and a Fellow of the Royal Photographic Society (Accredited Senior Imaging Scientist).

    In 2001 I founded the unique vascular optics measurement facilities at Newcastle's Freeman Hospital for patient microvascular assessments, establishing a platform for wide ranging collaborative research in clinical physiological measurement as well as medical device, sensor and signal / image processing development work. A main group assessed was those with a suspected auto-immune connective tissue disease including patients with Raynaud’s phenomenon.

    In early 2020, I was encouraged to apply to Coventry University for the new post of Professor in Biosensors and Bioinstrumentation at its new Research Centre for Intelligent Healthcare (CIH) in Healthcare Technology and Innovation. I started the new Chair position in July 2020 and I am fascinated to explore the power of light in medicine ("vascular optics"), with its many opportunities in microcirculation research for early disease detection. I have established specialist facilities for my microvascular research at Coventry as Specialty Lead in Vascular Optics and Microcirculation within the CIH.
