  • T32- DC00012 Training in Speech, Hearing and Sensory Communication

    The T32 Training Grant from NIH provides support for the interdisciplinary training program in Speech, Hearing and Sensory Communication at Indiana University. The program, provides specialized research training in the Communications Sciences and Disorders for postdoctoral and predoctoral trainees.

    In addition, the program also provides short-term summer research traineeships for medical students so they can gain first-hand experience in basic and clinical research. Faculty and laboratory facilities for the training program will be drawn from the departments of Psychology, Linguistics, and Speech and Hearing Sciences in Bloomington and the departments of Otolaryngology and Radiology in the School of Medicine in Indianapolis.

    The program has ten core faculty members and an additional twenty-six affiliated faculty, all of whom are carrying out research on a wide range of basic and clinical problems in the Communication Sciences and Disorders. Trainees will be expected to carry out research in one or more of the core or affiliated laboratories and gain specialized knowledge and expertise in areas such as: speech analysis, synthesis and perception; anatomy and physiology of the auditory system; psychophysics of hearing and complex sound perception; acoustic and articulatory phonetics; experimental and clinical phonology; perceptual development, phonological acquisition and development; tactile psychophysics and perception; clinical audiology, speech-language pathology, hearing impairment and cochlear implants; spoken word recognition and lexical access; and real-time spoken language comprehension processes.

    Postdoctoral trainees will be drawn from Speech and Hearing Sciences, Clinical Audiology and Speech-Language Pathology, Linguistics, Computer Science, Electrical Engineering, Cognitive Psychology and Sensory Psychology. Predoctoral trainees will be drawn from the Ph.D. programs in Psychology, Linguistics, and Speech and Hearing Sciences as well as the interdisciplinary Cognitive Science and Neural Science programs in Bloomington.

    As in the past, training activities will consist of: (1) individual and collaborative research projects in one of the core research laboratories; (2) participation in weekly laboratory meetings, research seminars, journal clubs and specialized workshops, and attendance at scientific or professional meetings; and (3) as needed, formal coursework in Psychology, Speech & Hearing Sciences, Linguistics, Cognitive Science or Neural Science. Access to clinical populations for research is available through the Speech and Hearing Clinic in Bloomington and the ENT Clinic at the IU Medical Center in Indianapolis. Our long-term goal is to provide broad interdisciplinary research training in the Communication Sciences and Disorders and to encourage novel and creative approaches to basic and clinical research problems in Speech, Hearing and Sensory Communication.

    Women and members of underrepresented groups are encouraged to apply. Indiana University is an Affirmative Action/Equal Opportunity Employer. NIH guidelines require that “the individual to be trained must be a citizen or a non-citizen national of the United States or have been lawfully admitted for permanent residence at the time of appointment.”
