His main research interest is to explore how insights provided by theoretical phonology and sociolinguistics can be applied to the investigation of the variable patterns that characterize the speech of second language learners. He also conducts research on the effects of computer technology (e.g., clickers, text-to-speech synthesizers, automatic speech recognition) on the acquisition of non-native languages. He teaches a variety of courses in related areas. Outside of academia, he works as a brand name evaluator, and experiences other worlds in the form of music, poetry and cinema.
