I’m an Assistant Professor of Cognitive Psychology at the Erasmus School of Social and Behavioural Sciences. Prior to working at Erasmus University Rotterdam, I was a member of Institut Jean Nicod and the KU Leuven Laboratory of Experimental Psychology.

I am currently serving as Executive Editor of the Review of Philosophy and Psychology (RoPP), a peer-reviewed journal edited quarterly at Institut Jean-Nicod and published by Springer.

My work on individual differences in language use is positioned at the intersection of quantitative psychology, philosophy of language, and cognitive linguistics.

I have expertise in the fields of concepts and categories, semantics, and psychometrics.
