Research Interests 

There is strong evidence that neural plasticity is an inherent property of the human brain; however the mechanisms underlying such plasticity remain obscure. My hypothesis is that plasticity in the human brain can be modulated by behavioural intervention both in health and disease. Consequently, behaviourally relevant intervention and recovery of impaired function, over time, will be associated with predictable changes in anatomical and functional measures of the brain. We use multi-parameter mapping to decompose the measured MR contrast to its main biological contributors – myelin, iron and water content, relate these to changes in behaviour and estimate the specific impact of brain tissue property changes on grey matter volume, density and cortical thickness.
We aim to establish a neurobiological explanation of neural plasticity mechanisms at the system level in order to understand how brain lesion patients’ functions recover. This will help clinicians to make (i) informed decisions as to which patients are most likely to benefit from which therapy approaches at which time point, and (ii) predictions about brain lesion patients’ recovery patterns and profiles.

Considering the promising results of diffusion weighted imaging (DWI) probabilistic tractography, our aim is to improve current techniques providing a more detailed picture of cortico-subcortical connectivity. The ultimate goal of our anatomical connectivity projects is the precise anatomical characterization of cortical and subcortical structures, which will help to optimise the accuracy of neurosurgery target planning and to predict clinical outcome in individuals undergoing deep brain stimulation (DBS).
