Elizabeth K. Hanson, Ph.D., CCC-SLP


Dr. Hanson earned her Ph.D. from the University of Nebraska – Lincoln in May 2005.  Prior to that she worked as a speech-language pathologist at the Communication Development Program/Communication Aids and Systems Clinic, which provides augmentative & alternative communication and assistive technology evaluation and intervention for people with complex communication needs in Madison, Wisconsin and the surrounding region.  She earned her M.S. at the University of Wisconsin – Madison in 1997.

University of South Dakota

Elizabeth K. Hanson (Liz) is an assistant professor in the Department of Communication Sciences and Disorders and teaches the following courses:

DCOM 434/534: Augmentative and Alternative Communication

DCOM 787: Theories & Methods of Research & Graduate Study

DCOM 724: Advanced Communication Science

DCOM 733: Neuromotor Speech Disorders

Dr. Hanson supervises graduate clinicians in providing evaluation and treatment for persons who benefit from augmentative and alternative communication (AAC) systems at the Department's Scottish Rite Speech & Hearing Clinic, and at off-site locations including SESDAC in Vermillion, SD; Avera-Sister James Nursng Home in Yankton, SD, and the MDA/ALS Clinic at Prairie Rehabilitation Center in Sioux Falls, SD.

Mission Statement

To improve the lives of people with communication disorders / complex communication needs by:


• Training graduate speech-language pathologists with in competencies in practice, especially AAC assessment and treatment (i.e., teaching).


• Asking and answering research questions to contribute to the clinical practice of speech-language pathology – specifically AAC (i.e., research).

Current Research Opportunities for Students

Students at the undergraduate and graduate levels are invited and encouraged to become involved with research in the Communications Sciences and Disorders Department at USD.  By working on a research project students will:

Develop skills that they will apply in their course work and future practices, related to problem-solving, analytic thinking, organization and time management, and interactions.

Gain practical experience that will increase their value to potential employers (research experience should be included on a student’s resume!).

Graduate and undergraduate students interested in learning more about student research are invited to contact Dr. Hanson at ekhanson@usd.edu or 677.5475 to make an appointment to discuss becoming involved in research as student investigators.


•Develop a better understanding of how research contributes to        practice in communication sciences and disorders.
