Tom Humphries

Dr. Tom Humphries is associate professor and associate director of the Teacher Education Program as well as associate professor in the Department of Communication at the University of California, San Diego. One strand of Humphries' current work focuses on how "talking culture" among Deaf people in recent history informs our understanding of cultural processes and how meaning circulates. In addition, he has developed a teacher training curriculum that uses a new construct: the application of indigenous bilingual teaching practices to classrooms of deaf children. He has published two widely used American Sign Language textbooks, Learning American Sign Language (Allyn & Bacon, 2004) and A Basic Course in American Sign Language (TJ Publishers, 1980). He is co-author (with Carol Padden) of Deaf in America: Voices From a Culture (1988) and the newly released Inside Deaf Culture, both from Harvard University Press. He received his Ph.D. in cross cultural communication and language learning from Union Graduate School. To contact Humphries, visit the UC San Diego website.
