I have been involved in Magnetic Resonance Imaging research since 1978 and as a PhD student was a member of the research group at Aberdeen University that developed “spin warp imaging”, one of the key MRI technologies that is still the basis of most MRI methods. Since then, I have worked at a variety of Universities, both in the UK and the US on both fundamental MRI physics and engineering and the application of MRI in the clinic. Before moving back to the UK to take up my current position at UEA, I led the brain tumour imaging research group at New York University.

Key Research Interests and Expertise
MRI is unsurpassed in demonstrating the presence of anatomical abnormalities throughout the body. However, it is often difficult to distinguish between different types of lesion from appearance alone. For example, the MRI appearance of some benign lesions can mimic the appearance of malignant tumours potentially leading to incorrect identification and inappropriate treatment. My main research interest is therefore in developing quantitative techniques that allow the resolution of these diagnostic problems, particularly in relation to cancer.
