Research Interests and Facilities
My research focuses on characterizing the brain’s white matter non-invasively using magnetic resonance imaging techniques. If the grey matter acts as the ‘service stations’ – then the white matter acts as the ‘motorways’ and hence forms an integral and fundamental part of brain networks. My research has been primarily focussed on development of methods for diffusion magnetic resonance imaging and fibre tractography – that allows us to study the three-dimensional pathways and connections of white matter bundles. This has led to important discoveries in both healthy and diseased states (see references). Tractometry is the name we give to quantifying additional aspects of white matter microcstructure along functionally relevant pathways, such as proxy indices of myleination (harnessed from techniques such as multi-component relaxometry and quantitative magnetization transfer imaging), and of axon morphology (including axon density and axon diameter, harnessed from advanced models of diffusion). The aim is to providing a more complete multi-spectral characterization of white matter – and therefore a more holistic view of the brain than functional imaging alone can provide.
I am the MRI Director of Cardiff University Brain Research Imaging Centre (CUBRIC), which is part of the UK’s largest 5* rated School of Psychology. This has state-of-the-art neuroimaging resources dedicated to neuroscience research. These include a 275-channel VSM/CTF MEG system, a 3-Tesla GE HDx MRI scanner, a 32-channel MRI compatible EEG system, two EEG laboratories, 2 TMS systems and a 300-node computing cluster dedicated to neuroimaging data analysis. CUBRIC also has dedicated support staff to support neuroimaging research.
