Roger J. Ingham is Professor of Speech and Hearing Sciences at the University of California, Santa Barbara. He was born in Australia and received his B.Sc. and Ph.D. in psychology (1972) from the University of New South Wales in Sydney, Australia. In 1982 he was awarded the Order of Australia. He has published 3 books and more than 160 papers, principally on developmental stuttering. His research has focused on the development of stuttering treatments, measures of stuttering, the neurology of stuttering and, most recently, its genetic basis. He is an ASHA Fellow and has been the recipient of several federally funded research grants for investigating stuttering. He is also an Adjunct Professor in the Research Imaging Center at the University of Texas Health Science Center at San Antonio where, in collaboration with Drs. Peter Fox and Janis Costello Ingham, he has developed a program of research on stuttering using brain imaging techniques including PET, event-related fMRI and transcranial magnetic stimulation.
