I am interested in the question: What is action? Here, I investigate via behavioral and psychophysiological measures (like EEG, ECG) what processes are involved in initiating, guiding, and evaluating the outcomes of action. Particularly errors and their cognitive processing play a crucial role in this regard. So more specific questions are: Why do people commit errors? How do we learn from errors and adapt our actions to cope with them? From a theoretical point of view, I aim to integrate perspectives from psychology, neuroscience, and movement/performance science, to stimulate and advance a “psychophysiology of action”. Also, I am interested in neuroscientific and statistical methods, in particular multivariate statistics in psychophysiology (e.g. independent component analysis or machine learning).
