Associate Professor of Psychology, Linguistics, & Neuroscience

Director of Human Imaging, Social, Life, & Engineering Sciences Imaging Center (SLEIC)


Biography:

Research Interests: 
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 age-related differences in language. My lab has examined semantic and phonological aspects of language comprehension and production. Most recently we have been examining neural factors that contribute to age-related decline in language production. We investigate the relations between structural factors (i.e., white matter integrity), functional activations, and behavior.
