is assistant professor at the Department of Psychology, University of Amsterdam. My research concerns the relation between brain and behavior in humans. I study cognitive control processes that link perception to goal-directed action and the underlying neurobiological mechanisms from a cognitive neuroscience perspective (Funding by NWO grants (VENI, Open Competition, and VanGogh)).

Central themes

are performance monitoring (the ability to adjust one's actions upon signs of error or conflict) as well as interference control (the coordination of conflicting responses). Other research fields involve attentional control (the selection of task-relevant information), and the ability to interrupt ongoing or planned actions.

My research tools

to track the dynamic control over voluntary actions are diverse, like reaction-time distribution analyses, neuropsychological tests, deep-brain stimulation and single-pulse and repetitive transcranial magnetic stimulation (TMS) and EEG. My focus is on individual and group differences in the normal population (ranging from children to recreational drug users) as well as on impaired cognitive control in clinical groups such as ADHD, dyslexia, and patients diagnosed with Parkinson's disease.
