Andrew Bowers received his Master of Arts in speech-language pathology from the University of Tennessee in 2007 and his Ph.D. from the University of Tennessee Health Science Center in 2012. Over the past five years, Andrew has worked as a part of a team at the University of Tennessee Stuttering Treatment and Research Program where he was involved in directing experimental protocols with people who stutter using choral speech and various forms of auditory feedback.

Andrew’s general area of interest is in the psychophysiological correlates of cognition and behavior in communication disorders. His research involves the collection and analysis of a wide range of physiological signals, including eye-tracking, manual kinematics, skin-conductance, electrocardiography (ECG), and electroencephalography (EEG). Recent multidisciplinary efforts toward identifying the EEG correlates of speech processing have been supported by collaboration in the fields of cognitive neuroscience, speech science, and auditory physiology.
