The human brain possesses a very complex and varied microstructure which plays a key role in its many functions. Furthermore, changes on these characteristics can be used as biomarkers for diseases such as tumors and strokes. This results in a high interest in the accurate description of the brain; however, this is not an easy task to accomplish. Diffusion magnetic resonance is a non-invasive imaging technique which can provide very rich information on such structures. This is achieved by probing the random movement of water molecules and describing related processes, such as molecular exchange through a cellular membrane.
My research mainly consists of experimentally investigating new sequences and models to describe such complex processes. This is done by conducting experiments in a research MR scanner and processing the output data from diffusion sensitive MR sequences.
