    Lyle L. Lloyd is Professor of Special Education and Professor of Audiology and Speech Sciences. His primary professional preparation was in audiology and speech-language pathology with cognates in special education, sociology, recreation and physical education. Lloyd's primary area of interest is the development of the transdisciplinary augmentative and alternative communication (AAC) field (both service and research) to promote full participation of individuals with little or no functional speech. Some of his specific areas of interest are test accommodations/adaptations and alternate assessment, cultural diversity issues of assessment and intervention, communication development and disabilities, and research and professional (both education and clinical) preparation. He holds the American Speech-Language-Hearing Association (ASHA) Certificates of Clinical Competence in both Speech-Language Pathology and Audiology.

    Lloyd has had wide experience in a number of settings, including public schools, universities, residential facilities, community clinics, and the federal government. His major research and clinical publications have focused on those with moderate, severe, and profound disabilities. While at Parsons State Hospital and Training Center in the early 1960's, he developed improved behavioral procedures for assessing the auditory abilities of individuals with severe and profound disabilities. Since coming to Purdue in 1977 as Professor of Audiology and Speech Sciences and Professor of Special Education, his major graduate teaching and research activities have focused on AAC. In 1984, Lloyd was a Fulbright Senior Research Fellow at the University of London.

    Lloyd has had a major involvement in a number of professional organizations such as the American Association on Mental Retardation (AAMR), ASHA, the Council for Exceptional Children (CEC), and the International Society for Augmentative and Alternative Communication (ISAAC) through elected and appointed positions as well as through a wide variety of convention presentations, including three ASHA short courses. Because of his broad research and clinical/educational experience, and his organizational skills, Lloyd served as program chair for the 1978 ASHA Convention. Lloyd is a Fellow in both AAMR and ASHA. He has also received the Honors of both the American Speech-Language-Hearing Association (2002) and CEC's Division for Children with Communication Disorders.

    He was one of the founding members of ISAAC and has served in several elected and appointed positions. From 1986-1994, he was editor of ISAAC's journal, Augmentative and Alternative Communication (AAC). More recently Lloyd served as Steering Committee Coordinator of the ASHA AAC SID (#12), chair of the Audiologists and Speech-Pathologists PSG (#6) of RESNA, and member of RESNA's AAC Working Group (which developed guidelines for AAC competencies and professional preparation). In recognition of significant contributions to the AAC field, Lloyd is the only person to receive both the ISAAC President's Award (1988, 1998) and the ISAAC Distinguished Service Award (1994). In addition to serving as editor of ISAAC's Journal, Lloyd has served as reviewer/consultant for several other journals including American Journal of Mental Deficiency, American Journal of Speech Language Pathology, Journal of Applied Behavior Analysis, Journal of Mental Deficiency Research,  Journal of Speech and Hearing Disorders, Journal of Speech and Hearing Research, and Mental Retardation.  He has also served as a consultant and reviewer for several government agencies and private foundations.

    In 2006 Lloyd received an honorary doctorate from the University of Pretoria based on his scholarship and leadership in the field of augmentative and alternative communication internationally and on his involvement in building research and training capacity in this field in South Africa.

    In addition to his national and international AAC leadership, Lloyd is involved at the local and state level through such activities as (a) the founding in 1986, of the Indiana Augmentative and Alternative Communication Consortium (IAACC), (b) active participation in the Indiana Speech-Language-Hearing Association (ISHA), including several terms on both the program committee and the AAC committee, and (c) member of the Executive Committee of the Purdue University Chapter of Sigma Xi Society for Augmentative and Alternative Communication (USSAAC).
