Research Interests
My research now centers around the use of structural and functional imaging measures to study the shifts in network architecture in the aging brain. I am specifically interested in how changes in structural and functional connectivity associated with aging impact the semantic retrieval of word or fact knowledge. Currently this involves asking why older adults have particular difficulty in certain kinds of semantic retrieval, despite the fact that vocabularies and knowledge stores typically improve with age.
A second line of research involves asking questions about how this semantic system is organized in young adults, understanding which helps form a basis for asking questions about older adults. To what degree are these semantic retrieval processes lateralized? What cognitive factors affect this laterality? How are brain structures like the corpus callosum involved in mediating distributed activation patterns associated with semantic retrieval?
I received my BA in Neurobiology from New College of Florida with Al Beulig, my MSc in Neuropsychology at University College London with Jon Simons, and my PhD in Psychology and Neuroscience from Duke University with Roberto Cabeza.
