My research focus is on the development and application of diffusion tensor imaging (DTI) and tractography for the understanding of neurological disability. Tractography uniquely allows the mapping of the white matter tracts of the living human brain. These methods can be used to reconstruct a wide range of clinically eloquent tracts such as the cortico-spinal tracts, fornix, optic radiations and uncinate fasciculus among others. A particular theme of research in which I have been active is the development of these methods for the purposes of neurosurgical planning in both children and adults. I am also using these methods to investigate the relationship between white matter damage and post-surgical deficits.
