Herbert Dunhill Professor of Neuroimaging
- FMRIB Physics Group
My group develops novel physiological MRI methods for the study of healthy and diseased brain.
I am particularly interested in techniques for mapping the macroscopic and microscopic neurovasculature. I collaborate closely with various clinical groups, in particular through the Oxford Acute Vascular Imaging Centre (AVIC), on the development of rapid imaging approaches to aid in the diagnosis and treatment of acute stroke. A second thread of research aims to advance ultra-high field imaging, utilizing our 7-tesla scanner. This research combines novel imaging hardware, including parallel RF transmission, with state-of-the-art acquisition techniques. Finally, I also work with the Dept of Psychiatry on the development of spectroscopic measurement of neurotransmitters.
I am an active member of University College and hold leadership roles in several imaging centres within Oxford (see links to left). In the broader scientific community, I have been active in the International Society for Magnetic Resonance in Medicine in a range of capacities.
