My research interests focus generally on numerical cognition and specifically on a phenomenon called spatial-sequence synaesthesia. Spatial-sequence synaesthesia is a condition in which units such as numbers, months, letters of the alphabet, etc. are experienced in spatially-defined arrays.

My first work aimed at investigating the nature of the assumed spatial mental number line by comparing the performance of number-form synaesthetes and a non-synaesthete population on different numerical tasks.

Another work is being conducted in order to test the assumed automatic feature of another sub type called month-form synaesthesia. In this work we use a combined haptics and virtual reality system.

Future fMRI study is being planned to examine which brain areas are involved when spatial-sequence synaesthetes are required to perform a numerical task.
