Fruzsina was a Research Associate on the MRC project Multimodal imaging of parietal brain networks in adults and children with developmental dyscalculia. Her PhD (in electrophysiology and numerical cognition) was achieved at the Eötvös Loránd University of Sciences, Budapest, Hungary, where she also received her MSc in cognitive psychology and electrophysiology. Her MSc thesis examined behavioural and electrophysiological measures of numerical processing in dyscalculic children. Prior to joining the Centre, Fruzsina worked in the Department of Psychophysiology, Research Institute for Psychology, Hungarian Academy of Sciences, Budapest. Fruzsina has worked alongside Dr Dénes Szücs examining how young children develop their representations of number (50%) and, prior to her current position, was the CNE's senior lab technician and part-time Research Assistant on the Analogy Project Humans as Analogy Makers. In 2012 she moved to work in EEG research at Addenbrookes Hospital and then took up a post as Research Fellow in Psychology at the University of Southampton.
