I am an Associate Professor at the School of Psychology and Artificial Intelligence at Radboud University Nijmegen and I lead the Computational Cognitive Science (CCS) group at the Donders Institute for Brain, Cognition and Behaviour.
My research interests span the cognitive sciences, including psychology, computer science, philosophy, cognitive neuroscience and AI. I have special interest and expertise in computational complexity theory and its applications in cognitive science.
