Michael WoletzDSC_0364

Michael Woletz is a PhD student at the Medical University of Vienna. During his studies in biomedical engineering, he gained a remarkable understanding of how to develop, apply, and optimize mathematical methods in order to solve various problems in medical research and beyond. His current research focus lies in optimizing preprocessing strategies, and he is developing technical solutions for TMS/fMRI applications such as online motion tracking.
