I am currently a senior lecturer in the Division of Applied Medicine at the University of Aberdeen and I am also an honorary Clinical Scientist in the NHS Grampian Department of Radiology. I am employed to provide physics support to the neuroimaging research program of the University of Aberdeen, and via SINAPSE, to the wider neuroimaging community in Scotland, to develop and assess imaging techniques and to carry out collaborative research on patient and normal control groups with academic and clinical colleagues, particularly collaborating with the Departments of Psychology, Mental Health, Public Health and Child Health. My main research interest has been in the developing and aging brain (particularly autism and Alzheimer’s disease). I am particularly interested in functional and structural correlations particularly with reference to changes in white matter during development/aging. I use a number of imaging and data analysis techniques, such as fMRI, optimised voxel based morphometry, diffusion tensor imaging with tractography, kurtosis imaging as well as T2 relaxography imaging to investigate mylination.
