RESEARCH INTERESTS

My research focuses on the links between speech production and speech perception and the implication of these links to the phonological structure of languages. The specific goal of my research program is to understand how the dynamics of tongue and vocal fold movement structure acoustic signals and perceptual processes. To support this program, I have been active in developing hardware and software platforms for measuring and simulating tongue and vocal fold motion.
