Michele Diaz is Professor of Psychology, Linguistics, and Neuroscience at Pennsylvania State University. She completed her M.A. in Psychology at Duke University as an NSF Graduate Research Fellow, conducting research in the Swaab Lab prior to completing her Ph.D. with Gregory McCarthy in 2004. Her work in the swaablab used ERP methods to examine how phonological and semantic expectations interact during spoken language comprehension.

Her current work examines age-related differences in semantic and phonological aspects of language production, focusing on how white matter integrity and functional brain activation relate to behavior. She also applies graph theory to study semantic memory networks, examining how these networks differ across age groups and other populations.
