Biography:

Language is a ubiquitous aspect of human life. Yet we are just beginning to understand the neural infrastructure that supports this complex social and cognitive function. Broadly, my research focuses on the relations between the brain and behavior. My lab has examined semantic and phonological aspects of language comprehension and production. Most recently I have been examining age-related differences in language. Specifically, this research project looks at neural factors that contribute to age-related retention (semantics) and decline (phonology) that have been observed in language production. We investigate the relations between structural factors (i.e., white matter integrity), functional activations, and behavior.
