Research focus

My research focuses on the cognitive and neural representation of other people’s and our own actions. Sepcifically I am interested in how actions are represented in different modalities (e.g. motor, visual, auditory) and how ((dis)similarities of) behavioural and neural representations of actions are mapped onto each other.

In this line of research data is acquired with functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG) and analyzed using multi-variate pattern analysis.

For exploratory analysis of multi-variate signals in fMRI data I have co-developed the ‘surfing’ matlab toolbox ( The majority of its functionality has been ported to Python and is available in PyMVPA; for the most recent code see
