The Linguistics Department offers a Ph.D. in Linguistics and a joint Ph.D. in Linguistics and Romance Languages. Student-initiated combined degree programs (e.g., Linguistics and Anthropology; Linguistics and Psychology are possible as well. The University of Michigan also provides students with diverse opportunities to acquire expertise in other areas that can complement their linguistics coursework and research, including a wide range of graduate certificate programs.
Fields of Study
The graduate program focuses on linguistics as a cognitive and social science. We offer strong theoretical grounding in phonetics, phonology, syntax, and semantics, as well as the opportunity to investigate the intersection of these subfields with language contact, sociolinguistics, historical linguistics, psycholinguistics, and computational linguistics. Students are encouraged to formulate and test theories of speakers' linguistic knowledge, and theories of linguistic variation and use, drawing on observational, experimental, and computational methods.
The program at Michigan takes a strongly interdisciplinary approach. Thus, in addition to the six research areas described below, the research agendas of many faculty and students bridge these areas (as is apparent from descriptions of faculty research interests and recent Ph.D. theses). In keeping with our long-standing interdisciplinary focus, close ties are maintained with the Departments of Anthropology, Computer Science, Philosophy, and Psychology, as well as the language departments and the English Language Institute. Many Department faculty also specialize in particular languages or language areas, including Chinese, Germanic, Indo-Aryan, Romance, and Salishan languages, and languages of North West and sub-Saharan Africa. Several faculty members are also experienced fieldworkers, offering expertise in a variety of field methodologies and in the preparation of descriptive grammars and dictionaries.
Steven Abney specializes in computational linguistics, particularly parsing and language learning. Ezra Keshet has interests in computational semantics. Drago Radev (School of Information and Linguistics) specializes in computational linguistics in information systems, especially summarization and question answering. Richmond Thomason (Philosophy and Linguistics) has interests in natural language generation and dialogue systems. Richard Lewis (Psychology and Linguistics) studies computational models of human sentence processing.
Among the themes of faculty members' historical linguistic interests are sound change, methods and practice in establishing language families, language contact and the relation between language change and cognitive and social factors. Sally Thomason specializes in changes resulting from language contact; she also studies deliberate linguistic changes and (mainly from a skeptical viewpoint) proposals for long-distance relationships. Bill Baxter specializes in Chinese historical linguistics; he also has strong interests in questions of distant linguistic relationships. Pam Beddor, primarily a phonetician, investigates phonetic routes to sound change. Steve Dworkin is a historical Romance linguist, with a special emphasis on processes of lexical change. Ben Fortson specializes in Indo-European linguistics. Acrisio Pires, primarily a formal syntactician, investigates syntactic change in connection with language acquisition. Robin Queen, a sociolinguist, focuses on interactions among language contact, language ideology, and language change. The historical linguistics group in the Department is augmented and strengthened by research on language history being carried out by other faculty in this and other departments at the university, as well as by faculty in neighboring universities.
The research interests of the phonetics and phonology faculty converge in relating phonological (cognitive) representations to their physical instantiation, and in the experimental investigation of spoken language. San Duanmu specializes in phonology, with a focus on using quantitative or corpus data to evaluate phonological entities, such as segments, features, and syllables, both within and across languages. Patrice Beddor and Jelena Krivokapić specialize in phonetic theory. Beddor's current research investigates the production and perception of coarticulation and their consequences for sound change. Krivokapić studies speech prosody; she investigates the relation between prosodic representation and articulation, acoustics, and perception. Andries Coetzee's work straddles the boundary between phonological and phonetic theory, with a particular focus on the relation between perception and production. All four faculty also have special interests in variation, which are shared by intonation specialist Robin Queen. The Department's historical linguists provide further phonological expertise to our curriculum. Colleagues from other departments with interests in speech and phonological processing include Julie Boland and Ioulia Kovelman (Psychology), Greg Wakefield (Computer Science & Engineering), and faculty at the Kresge Hearing Research Institute.
Research in this domain falls into two primary areas: sentence comprehension and language acquisition and processing across the lifespan. The research on comprehension (Jon Brennan, Julie Boland, Richard Lewis) focuses primarily on syntactic parsing and its relationship to lexical and semantic processes. These cognitive processes are studied using multiple experimental techniques (e.g., eye-tracking, reaction time paradigms, electroencephalography/EEG, magnetoencephalography/MEG and functional magnetic resonance imaging/fMRI) and computational modeling. Research in the psychology of language across the lifespan investigates first and second language acquisition and bilingualism in children and adults (Sam Epstein, Carmel O'Shannessy, Acrisio Pires) and the relationships among language, social and cognitive factors in aging (Deborah Keller-Cohen). Faculty from other departments with related interests include Nick Ellis, Susan Gelman, Ioulia Kovelman, Frederick Morrison, Thad Polk, and Twila Tardif (all from Psychology), and Diane Larsen-Freeman (the English Language Institute and School of Education).
These overlapping subfields of linguistics examine language variation and language use, with a concern for developing theoretical insights into the ways that situations, identities and macro-level social, cultural, and political factors relate to beliefs about language, to language structure and use and to theories of language. Sociolinguistics, which relies on both quantitative and qualitative analysis, covers a broad range of topics, including bi- and multilingualism, language variation and change, language attitudes, ideologies about language and language standardization (Carmel O'Shannessey, Robin Queen). Language Contact covers multilingualism, language change, pidgins and creoles and the effect that contact among people has on linguistic structure and language use (Marlyse Baptista, Carmel O'Shannessy, Robin Queen, Sarah Thomason). Discourse analysis focuses on the qualitative and corpus-based analysis of spoken and written texts (Deborah Keller-Cohen). Faculty working in these areas share interests in sociophonetics that overlap with colleagues in phonetics and historical linguistics and in syntax that overlap with colleagues in theoretical syntax and semantics. Faculty from other departments with related interests include Bruce Mannheim, Judith Irvine, Webb Keane, Barbara Meek, and Alaina Lemon (Anthropology), Anne Curzan (English), Renee Anspach (Sociology), and Lesley Rex (Education).
Acrisio Pires and Sam Epstein share an interest in developing explanatory, restrictive theories of human syntactic and semantic knowledge. (Daniel Seely, a faculty member from Eastern Michigan University, also shares this focus and works closely with the faculty and students interested in this area of research.) Each works within a Chomskyan framework, with particular attention to the exploration of the Minimalist Program. Pires is particularly interested in explaining Agreement and Control Phenomena and Epstein continues to develop the so-called "Derivational Approach" to syntactic relations. Ezra Keshet conducts research in the area of semantics. Each faculty member has a strong interdisciplinary outlook, as do Rick Lewis and Julie Boland, who investigate psycholinguistic theories of syntactic, semantic and lexical information flow during sentence processing.
