Field of Research
The focus of my group is structural and functional imaging in neurological diseases with a particular focus on epilepsy. As a neurologist I am interested in better understanding the neuro-biology of specific diseases and translating this information to better patient care and earlier diagnosis. To this end we apply several computational, post-processing methods including voxel-based morphometry, machine learning and network analysis based on MRI, MEG and HD-EEG.
In epilepsy we are interested in better defining the structural abnormalities associated with seizure generation (“epileptogenic zone”) by means of structural imaging including high-field MRI (3T and 9.4T) and post-processing. Moreover, we apply diffusion-tensor imaging to analyze how epilepsy and seizures affect the structural networks of the brain. On the functional side we use functional MRI together with high-density EEG (256 channels) and MEG to asses functional networks characteristics and spread of ictal discharges i.e. epileptic activity. This broad range of non-invasive methods provides us with comprehensive access to brain networks in humans and in-vivo.
