Cognitive Neuroscience of Speech and Language
Our discovery science goal is to provide biologically and psychologically plausible accounts of human communication and its disorders.
Current areas of research focus include: (a) laterality and sex differences in healthy adult speech and language; and (b) cognitive neurorehabilitation of acquired speech and language disorders.
