Research interests

My main research focus is on applying state-of-the-art methods from digital signal processing and machine learning to the development of diagnostic support in various clinical fields. One strong focus in recent years has been on recognizing patterns in electroencephalograms (EEG), and scoring such data in sleep medicine. An example is the automated staging of sleep based on EEG and other biosignals such as electrooculography (EOG) and electromyography (EMG) according to international standards. Another focus is the use of machine learning methods for predicting diseases or their outcome, as well as modelling their uncertainty toward more robustness.
