Biography and Research Interests

At the end of his studies at the Ecole Normale Supérieure de Lyon, Professor Thierry gained his PhD in Toulouse under the supervision of Prof. Jean-Francois Demonet in 2000. Shortly after he graduated he was offered a Lectureship in the School of Psychology at Bangor University where he is now Professor of Cognitive Neuroscience and Director of Innovation for the Pontio project. Using experimental psychology (e.g., reaction times, error patterns), functional brain imaging (functional Magnetic Resonance Imaging, fMRI, and Positron Emission Tomography, PET) and Event-Related Potentials (ERPs) Dr Thierry has studied language comprehension in the auditory and visual modalities, and, in particular, semantic access. In the past seven years, Dr Thierry has investigated a range of themes, such as verbal/non-verbal dissociations, visual object recognition, functional cerebral asymmetry, language-emotion interactions, language development, developmental dyslexia and bilingualism. Dr Thierry’s current main interests are (a) the levels of integration of the two languages of bilingual infants and adults at lexical, syntactic and semantic levels, studied using behavioural measurements, ERPs, fMRI and eye-tracking; (b) the mechanisms of semantic priming in both the verbal and nonverbal domains in the infant and the adult using ERPs and fMRI, i.e. the fundamental aspects of neurosemantics.
