I am an Essex-born, Oxford-trained clinical academic and biochemist. I am Professor of Metabolic and Physiological Imaging at the University of Liverpool, where I also chair the University Committee on Research Ethics. My main research expertise is the quantitative interpretation of physiological and biochemical data in vivo, particularly using magnetic resonance spectroscopy and imaging methods. I have authored about 400 research papers and supervised about 40 doctoral students. At the NHS University Hospitals of Liverpool Group I am an Honorary Consultant Chemical Pathologist and an appointed member of the Council of Governors.
