My main research objective is to elucidate the cortical and behavioural processes involved in high-level human perception across the main sensory systems. This interest is motivated by the fact that perception is not a fixed concept since it is significantly modulated by information from other senses and other contextual factors such as past experience, internal predictions, on-going motor behaviour and the working range of the sensory system. Furthermore, Perception is the basis of Cognition, and an understanding of the mechanisms behind how we perceive provides a better route to understanding other high-level human functions. To date, my team and I have begun to shed light on some of the behavioural principles of how the senses interact with one another to form a unified perception of our world. The current challenge is to provide a better understanding of the cortical and genetic mechanisms behind these principles. To this end my team are conducting a series of studies investigating cortical correlates of multisensory perception using neuroimaging (i.e. fMRI and EEG) technology and, in collaboration with colleagues the Smurfit Institute of Genetics at TCD we are investating behavioural and neural correlates of synaesthesia. Lately, I have begun to develop my research towards a better understanding of multisensory processing in the normal, damaged and ageing brain through collaborations with colleagues in the School of Medicine, TCD. Finally, in collaboration with colleagues in Computer Science and Mechanical Engineering, we are currently investigating how virtual displays of crowd scenes can be improved by multisensory stimulation.
