Scientific background
I have been interested in the research of diagnostics and epilepsy surgery treatment since 2011, first as a PhD student, subsequently as a postdoctoral researcher and today as the leader of the Clinical Electrophysiology research group of EpiReC. I work as a researcher and supervisor of future colleagues at the Faculty of Electrical Engineering, Czech Technical University in Prague, where we develop and provide technical background and support for the clinical research at Second Faculty of Medicine, Charles University and Motol University Hospital.
Research interests
My research focuses on the development of advanced digital biosignal processing methods to analyze mainly intracranial EEG, High-Density-EEG and neuroimages as diagnostic tools for surgical treatment of epilepsy, as well as a better understanding of the driving mechanisms within epileptic networks. The main scope of my research is the identification of pathological markers in intracranial EEG, analysis of effective/functional connectivity, description of brain networks, and image-processing of MRI, CT and PET scans as assistive neuroradiologist tools within neurosurgery planning. I am also involved in EpiReC research of cognitive functions.
