About Me

Educational Background

Carol completed a BS in Child Development from Colorado State University, a PhD in School Psychology - Developmental Neuropsychology from the University of Northern Colorado,  a Postdoctoral Fellowship emphasizing the electrophysiological correlates of speech perception in infants, children, and young adults from Southern Illinois University-Carbondale and a second Postdoctoral Fellowship in speech physiology and developmental speech motor control from the University of Arizona. 


Research Program

Her primary research focus is on the developmental aspects of speech motor control in healthy children children with neurogenic communication disorders. Specifically, her studies address the development of the respiratory subsystem and its coordination with the other speech subsystems for vocalization and speech.  More recently, Dr. Boliek has employed structural and functional neuroimaging methodology to explore neural changes following intensive voice treatment (LSVT LOUD) with children who have motor speech disorders secondary to cerebral palsy.   In addition, she has established a series of transcranial direct current stimulation (tDCS) protocols to prime or enhance speech motor control.
