Research interests
My main research interest is the application of functional magnetic resonance imaging to further understand and advance non-invasive brainstimulation techniques, mainly transcranial magnetic stimulation. More precisely, I explore direct effects of TMS using interleaved TMS-fMRI. My emphasis is on understanding different aspects which could influence variability in TMS effects and thus also treatment response. Furthermore, I use neuronavigation techniques as well as electric field modelling to optimize workflows and gain further insights on potentially highly influential factors for TMS success.
