I am currently awaiting formal PhD graduation following the approval of my thesis corrections. I have been funded through the Neuroinformatics and Computational Neuroscience Doctoral Training Centre (DTC) and a member of the Institute of Adaptive and Neural Computation (IANC) at the University of Edinburgh.

What's new

I have recently worked with Amos Storkey and Richard Phelps on a renal failure detection project.

What I did (PhD)

I worked with Amos Storkey and Mark Bastin to develop methods for the analysis of diffusion MRI data. We used Bayesian modelling to look at the pathways connecting different regions of the brain.

In paticular, I was interested in estimating the volume of these pathways with precision greater than the acquisition voxels. This requires the removal of ambiguity associated with partial volume effects, where more than one tissue type is present in a voxel.

In order to make this estimation as robust and efficient as possible, I looked into several classes of Bayesian machine learning methods:

Given that the brain images we work with typically comprise 106 voxels, I used distributed computation and ran my code on Eddie.
