My research is focussed on how individual differences in perception (e.g., synaesthesia) affect higher cognitive functions (e.g., memory). In relation to that, I am also interested in how individual differences such as synaesthesia develop and whether they can be acquired through training. Moreover, I do have a strong interest in memory processes.
