My research is concerned with the processes of semantic cognition – i.e., the ways in which we (a) maintain a store of conceptual knowledge about objects, words and people and (b) use executive control processes to access this information in a flexible, task-appropriate manner. I explore this using a variety of techniques, including:

• Case-series neuropsychological investigations, primarily of patients with semantic dementia and semantic deficits following stroke
• Computational linguistic analyses (e.g., latent semantic analysis)
• Repetitive transcranial magnetic stimulation in healthy subjects
• Functional neuroimaging studies
• Connectionist computational models

I am broadly interested in cognitive neurosciences; within this field my research focuses on categorization processes and language, and by extension, language disorders. I also enjoy studying and developing methodological tools to analyze data coming from MRI, fMRI and EEG systems.
