He has headed the Image Guidance Lab for many years and was significantly involved in the introduction and further development of navigated TMS for neurosurgical planning. Among others, his lab has developed presurgical risk stratification models, which allow to better prepare patients for intraoperative neurophysiology. In cooperation with the Humboldt-Universitaet zu Berlin, his lab is currently exploring how new visualization methods like stereoscopic projections or head-mounted-displays can benefit clinical work and how current workflows and interfaces can be improved to account for the ongoing technological shift.
