Bio

I received my B.A. in Psychology from Saint Anselm College in 2001 and my Ph.D. in Experimental Psychology from Tufts University in 2008. My dissertation work focused on the time course of the neural representations underlying object recognition using event-related potentials (ERPs). I am interested in extending my research on object recognition to the study of word recognition and more specifically, impaired word processing in dyslexia. I am interested in establishing the time course (ERPs) and where in the brain (fMRI) phonological and orthographic processing take place during word recognition and how this processing may be disrupted in dyslexia.
