Research focus: I have a broad interest in human information processing with a particular emphasis on selective attention and working memory. One key question is what happens if distractors capture attention and/or enter working memory and how this is usually prevented. In my work, I use psychophysics, neuroimaging (EEG and fMRI) and cognitive modelling. Recently, I started combining the respective strengths of neuroimaging and modelling by integrating the timing of neural correlates of cognitive processes into explicit mathematical models of these processes and their interactions.
Key words: attention, working memory, visual cognition, electroencephalography, model-based cognitive neuroscience
