Koen graduated in 2017 from the University of Leuven, where he completed the Theory and Research Master in Psychology. During his internship in the lab of Prof. Peter Kuppens, he looked into the role of personality on the temporal dynamics of emotions and emotion regulation strategies. In his Master's thesis, supervised by Prof. Bilge Sayim, he investigated whether the uncrowding of word segments by contrast polarity increased peripheral reading performance. Currently, as a Ph.D. candidate, he focusses on the relation between crowding and reading performance by means of psychophysics and eye-tracking studies.
