Ilse Coolen

Ilse Coolen is currently a postdoctoral fellow at LaPsyDÉ at the Université de Paris, under supervision of Dr André Knops, where she works on a behavioural longitudinal study exploring numerical cognition in 3-to-9-year-old-children. Ilse obtained her B.Sc. and M.Sc. degrees in Clinical Psychology from the Vrije Universiteit Brussel, Belgium. In 2018, she received her PhD at the University of Hull, UK, where she studied domain-general and domain-specific predictors of mathematics achievement in a longitudinal study in primary school children. After her PhD, Ilse joined the Attention, Brain & Cognitive Development lab at the University of Oxford, UK, working on a study in preschool children exploring emerging early numerical skills. Her research aims to understand the cognitive mechanisms of mathematical development in preschool and primary school children.
