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. I've also been involved in the EU-funded CITRUS-project, which aims to develop a prototype for combining focused ultrasound neuromodulation with MR-based monitoring and read-out.
