Biography:

Jackson T. Gandour received his BA in political science from Wheeling Jesuit University in 1963. He developed an interest in tone languages during his service as a Peace Corps Volunteer in Thailand (1964-66). After receiving his MA in linguistics from the University of Pittsburgh (1968), he taught linguistics as a Visiting Fulbright Lecturer at Niigata University in Japan (1968-69). He later returned to Thailand (1975) to carry out multidimensional scaling research on tone perception for his PhD in linguistics at UCLA (1976), and continued this research as a postdoctoral fellow at Bell Labs (1976-77). He then came to Purdue University where he has been a faculty member in the Department of Speech Language and Hearing Sciences for 37 years. As a Senior Fulbright Research Scholar at Mahidol University (1988-89), his research interests focused on tone perception and production in adult speakers of Thai with communication disorders, i.e., aphasic, laryngectomized, and hearing-impaired individuals. Later on, he used functional brain imaging techniques (PET, fMRI) to study speech prosody in healthy adult speakers of Mandarin Chinese and Thai (1996-2007). His current research exploits auditory electrophysiology (MMN, FFR, CPR) to investigate pitch encoding in tonal languages at both cortical and brainstem levels of the brain (2003-present). He was a Visiting Professor in the Department of Linguistics at the University of Hong Kong (2012). He served on the editorial boards of Brain and Language (1993-2011) and Aphasiology (2002-2011).
