Research & Teaching Interests:  My research program has focused on auditory-visual integration in spoken language processing, co-speech gesture, second-language speech production, and the applications of technology in perception and production training of the segmental and suprasegmental aspects of language. Current projects address the relationships among learner variables, language use factors, and interlocutor type in the development of the component skills of oral interaction ability by L2 learners of English. A project supported by CLEAR recently investigated the development of oral skills for participants in short-term study abroad programs to Germany and Japan. A project supported by CeLTA explored the relationship between learners’ oral communication strategies in the second language and their abilities. Eye tracking is also being used to investigate the effects of task difficulty on L1 and L2 auditory-visual speech perception. Teaching interests emphasize the integration of theory, research, and practice in the professional development of second language acquisition specialists and classroom language teachers.  At MSU, I have taught courses on second language acquisition, research methods in language learning and teaching, L2 phonetics and phonology, and a seminar on second-language speech. I also serve as the Director of the M.A. TESOL Program, coordinator of undergraduate LLT courses taught by our graduate student instructors, and as a member of the editorial board of the journal Language Learning & Technology and the Journal of Second Language Pronunciation.
