Oliver Wendt is Assistant Professor in the Departments of Speech, Language, and Hearing Sciences, and Educational Studies at Purdue University. He received a B.S. in Education and Psychology from the University of Cologne-Germany in 1996, a M.S. in Special Education from the University of Nebraska-Lincoln in 1998, a M.S. in Rehabilitation Sciences from the University of Cologne-Germany in 2000, and a Ph.D. from the Transdisciplinary Augmentative and Alternative Communication Program at Purdue University in 2006.
His current research investigates the efficacy of augmentative and alternative communication (AAC) strategies including graphic symbols, Picture Exchange Communication System, and speech-generating devices for individuals on the autism spectrum that present with little or no functional speech. Dr. Wendt specializes in single-subject experimental designs and meta-analyses of these studies. He is first editor of the textbook “Assistive Technology. Principles and Applications for Communication Disorders and Special Education” (Emerald Publishing). Dr. Wendt serves on the editorial boards of the American Journal of Speech-Language Pathology, Augmentative and Alternative Communication, Evidence-based Communication Assessment and Intervention, and Evidence-based Practice Briefs. He is the 2005 recipient of the Editor Award for the Most Significant Research Article in Augmentative and Alternative Communication (together with Schlosser, Angermeier, & Shetty).
In addition, Dr. Wendt is co-founder of an AAC software company by the name of SPEAK MODalities LLC, which is dedicated to providing the best evidence-based AAC solutions for developing communication, speech, and language skills in individuals with autism and/or severe communication disorders.
