Research Summary
I develop tools for the analysis of diffusion MRI data of the brain. I am interested in biophysical modelling of brain connections at different scales, both for resolving tissue microstructural patterns and long-range brain connectivity. I develop computational methods for inferring this information in-vivo and I am particularly interested in data fusion approaches for combining strengths and bridging the gaps across structural modalities (for instance, diffusion MRI at different k/q-space acquisitions, histology, microscopy). I am also heavily involved with the design and implementation of new technologies that aim to improve the spatial and angular resolution of diffusion MRI acquisitions.
More specifically, I am currently involved in the following projects:
- The recently funded EPSRC project on "Anatomy-Driven Brain Connectivity Mapping".
- The Human Connectome Project (funded by the US NIH)
- The developing Human Connectome Project (funded by ERC)
- The UK Biobank Imaging Study
