I study language and cognitive processes using behavioural, computational, and neuroscience methods. The major focus areas of my research are (1) how conceptual (semantic) knowledge is organized in the mind and brain and (2) language deficits and recovery after left hemisphere stroke (aphasia). My research in these areas aims for "Pasteur's Quadrant" -- to answer fundamental questions in cognitive science and neuroscience in a way that has practical applications, such as new insights into language impairments and helping to develop better rehabilitation strategies.
