My research focuses on answering questions in theoretical phonology using techniques from a wide variety of areas, including experimental phonetics, psycholinguistics, sociolinguistics, semantics, and information theory. The kinds of questions I am interested in are: what discrete categories of sound do language users extract from a continuous acoustic signal? what relationships may hold between these sound categories in a given language? what patterns and processes apply to these categories? what linguistic information do these categories convey? how do language learners acquire these categories? to what extent are these categories, relationships, and processes psychologically real? what cognitive processes have led to these categories, relationships, and processes? how can these categories, relationships, and processes be modeled in an objective and predictive way?
