Robert Bayley teaches courses in sociolinguistics, second language acquisition, and general linguistics. His research focuses on language variation and language socialization, especially in bilingual and second language populations. Currently, he is investigating the role of frequency in phonological and morphosyntactic variation in English and Spanish. In addition, he is collaborating with Professor Rebecca Ambrose of the UC Davis School of Education on a four-year project to strengthen mathematics teaching and learning, particularly for English language learners, in an elementary school district in North Sacramento.

Professor Bayley is co-author or editor of nine volumes including Language as Cultural Practice: Mexicanos en el norte (with Sandra Schecter, 2002), Sociolinguistic Variation: Theories, Methods, and Applications (with Ceil Lucas, 2007), and The Oxford Handbook of Sociolinguistics (with Richard Cameron & Ceil Lucas, 2013). He has also published numerous articles and chapters on sociolinguistics, bilingualism, and second language acquisition. His grants, fellowships, and awards include three Fulbright Senior Scholar Awards to Bolivia and Mexico, research grants from the National Science Foundation, the Spencer Foundation, the California Postsecondary Education Commission, the Texas Education Agency, and the U.S. Department of Education, and a National Academy of Education Spencer Postdoctoral Fellowship. In 2002 he was awarded an honorary professorship by Harbin Institute of Technology in China and the University of Texas at San Antonio President’s Award for Distinguished Achievement in Research. In 2003, he served as the Fulbright-York Chair in Linguistics at York University. In 2011 he was named a Hai Tian (Sea-Sky) Scholar by Dalian University of Technology in China and, together with colleagues Carolyn McCaskill, Ceil Lucas, and Joseph Hill, he received the Andrew Foster Humanitarian Award from the National Black Deaf Advocates for the book and DVD, The Hidden Treasure of Black ASL: Its History and Structure. In 2013 he was elected as Vice President and President-Elect of the American Dialect Society.
