Adam Buchwald takes an interdisciplinary approach to address the questions of how we produce and perceive spoken and written language. His primary research focuses on describing the linguistic information that is neurally represented and manipulated during language processing tasks. To achieve these goals, Buchwald's research includes detailed studies of the performance of neurologically impaired populations with acquired language deficits (e.g., aphasia, apraxia of speech) as well as neurologically intact populations, and incorporates the research methods of several disciplines including speech science, cognitive neuropsychology, psycholinguistics, and theoretical linguistics. Buchwald completed his Ph.D. in the Department of Cognitive Science at Johns Hopkins University in 2005, and completed a two-year post doctoral fellowship in the Department of Psychological and Brain Sciences at Indiana University.
