Wim De Neys


Full researcher


Wim De Neys is a Research Director at the French National Centre for Scientific Research (CNRS). After earning his Ph.D. in cognitive psychology at the University of Leuven (Belgium) and post-doctoral training at the University of California Santa Barbara (USA) and York University (Toronto, Canada) he joined CNRS in 2009. In his work on human thinking, he uses a combination of behavioural, neuroscientific and developmental methods to unravel how intuitive and deliberate thought processes interact.
