Alexander Sack is Professor of Brain Stimulation and Applied Cognitive Neuroscience at Maastricht University. Sack is one of the world’s foremost pioneers and influential leaders in brain stimulation research and a renowned expert in combining brain stimulation with brain imaging techniques. Sack repeatedly made theoretical & methodological scientific breakthroughs on these topics, publishing >200 articles in highest ranking journals. His group pioneered the development of simultaneously implemented TMS-fMRI-EEG during cognitive behavior, allowing to apply brain-stimulation while recording the individual brain network (fMRI) and oscillation (EEG) responses of cognitively engaged participants. Prof. Dr. Sack has received several grants and awards, enabling him to develop a larger scale interdisciplinary basic research project on neural network communication mechanisms and to translate these findings into clinical applications for treating various neuropsychiatric brain disorders.
