Background

Before joining ARU in 2017, Dean was studying atypical development at Birkbeck, University of London, and investigating the effects of bilingualism on brain and cognitive development at UCL.

For his PhD, which he completed under the supervision of Professor Annette Karmiloff-Smith and Professor Mark Johnson at Birkbeck’s Centre for Brain & Cognitive Development, Dean investigated early cognitive and neurophysiological processes that underlie language development in infants at high risk of developing autism and children with different neurodevelopmental disorders (Down syndrome, fragile X syndrome, Williams syndrome).

Research interests

Dean is interested in typical and atypical neurocognitive development. He is particularly interested in understanding how early language and cognitive abilities emerge in typically and atypically developing populations, by studying the interplay of various factors (eg visual attention, multimodal integration, parent-child interaction) across domains, modalities, and levels of description, over developmental time.
