Research Abstract:

Our lab uses behavioral, functional neuroimaging (fMRI) and functional connectivity (fcMRI) to study the neural mechanisms underlying attention, language, learning and memory. One area of research is the development of neural mechanisms underlying reading from ages 7 to adulthood with an emphasis on how visual regions in the brain change as people become fluent readers. The second focus is on identifying and characterizing fMRI and fcMRI signals related to task organization and executive control.
