Research and Clinical Interests
Dr. Lewis received her bachelor’s and master’s degrees from Portland State University, and her Ph.D. from Northwestern University. She holds the rank of professor at UNR and is a Fellow of ASHA. Her areas of interest include fluency disorders, resonance disorders and research design and measurement. She is a Board Recognized Fluency Specialist.
Dr. Lewis’ interest in research design and measurement extends to helping students learn about and actively participate in the research process. Her current research focus is on the assessment of resonance disorders and the identification and measurement of stuttering behaviors.
Her clinical work focuses on the treatment of stuttering in adults and the development of school-based treatment programs for children who stutter. She serves as a consultant to school districts in Nevada, helping to develop service delivery models which meet the needs of school-age children who stutter.
