My work is aimed at (i) characterizing the neural organization of language and other cognitive domains, (ii) understanding how these systems interact at the behavioral and neural levels, and (iii) determining the factors that give rise to brain organization for cognition. In addition to studying traditional populations, I've investigated these questions through the study of two special populations: deaf individuals who use sign language, and individuals with Williams' syndrome, a rare developmental disorder that affects various cognitive abilities non-uniformly. My research approach tends to be methodologically eclectic encompassing techniques such as traditional neuropsychological lesion studies, gross brain morphometry, functional magnetic resonance imaging (fMRI), and magnetic source imaging (MSI). Other areas of interest include the neurobiology of auditory speech perception, aphasia, and neural plasticity.
