Current Research
My research is focussed on the development and application of multi-modal functional brain imaging. I have been active in this field for nearly 20 years and I have published over 100 papers in leading journals, on topics including MEG, MRI, fMRI and EEG.
My primary area is Magnetoencephalography (MEG) - the process of inferring electrophysiological brain function via measurement of magnetic fields generated by current flow in neural assemblies. I have developed new methods for mathematical modelling of MEG data, in particular to enable source localisation, and to measure functional connectivity. Such measurements have had impact in both basic neuroscience and are currently being applied in multiple clinical scenarios including schizophrenia and concussion.
Recently, our group has also focussed on development of MEG hardware, and in particular the promise of new compact and highly sensitive quantum enabled sensors for magnetic field measurement. Our group, working in collaboration with industry, have designed and fabricated one of the most advanced brain imaging systems in the world. Unlike conventional systems, this instrument allows complete flexibility to adapt to any head shape or size, it enables free movement of the participant during data collection, and provides increased sensitivity and spatial specificity.
My research is backed by major grants from the EPSRC, Wellcome, and MRC. I also collaborate widely within the UK and worldwide.
