Research Statement

My research has centered on development and evaluation of treatments for apraxia of speech (AOS) and aphasia. A secondary emphasis has concerned examination of the nature of AOS.  In particular, I have been interested in explicating variability associated with AOS. In addition to clarifying the nature of the disorder, the understanding of variability is crucial to the implementation and interpretation of single-subject experimental methods and thus, also relates to my treatment research. The treatments developed and tested in my laboratory are theory-driven. However, an overriding goal of my research program continues to be the development of clinically applicable treatments.
