i am a linguist and a phonetician at the unversity of california at berkeley. my affiliation at uc.berkeley is with the department of linguistics and i serve as the director of the uc.berkeley phonology lab.
before coming to berkeley i earned a phd from ohio.state.univerity. then i had a post-doctoral fellowship at indiana.university, and another post-doctoral fellowship at UCLA. after my post-docs i had a research professorship at the university.of.alabama medical school in birmingham.alabaman for one year and then taught for 10 years back at my alma mater ohio.state.university. in 2005 i joined the linguistics faculty at uc.berkeley as a full professor.
the main ideas that i pursue in my research center around the nature of phonetic knowledge. i am a proponent of the idea that phonetic knowledge is best thought of as inclusive of all of one's experiences as a speaker or hearer. i have implemented this conception of phonetic knowledge in exemplar-based models and find that this style of modeling - in which, no processes of abstraction remove gradient information from memory - provide a better fit to the behavior of listeners.
i have also made some basic phonetic descriptive contributions, in providing descriptions of xhosa clicks, cherokee tones, tamil liquids, korean stops, creek vowels, and the speech of gay men in columbus, ohio.
ultimately, linguistic phonetics is concerned with how phonetic factors influence the sound patterns of language. to me this means that explaining sound change is the ultimate goal of linguistic phonetics. so, i've done some theoretical and modeling work on sound change.
recently i have been helping a team of researchers at uc.san.francisco conduct research in phonetic neuroscience. this work involves imaging the brain during speech production and perception with the aim of providing basic facts about the neural coding of phonetic knowledge.
i teach introductory linguistics (for freshmen), phonetics, and psycholinguistics. follow the 'courses' menu items to links to courses. additionally i have written two textbooks and revised and edited a classic textbook in phonetics. follow the 'books' menu item to see information about these books. i would highlight here the web site that goes with peter ladefoged's 'a course in phonetics' because access to this site is free, despite the efforts of the publisher to make students pay for it.
