Yunjung is a professor in the School of Communication Science and Disorders. She typically teaches a graduate course (SPA 5230 Motor Speech Disorders) in fall. Her primary research interests lie in the transformation from a talker’s articulatory behavior to listeners' reaction. Specifically, her work has focused on identifying acoustic and articulatory characteristics of speech produced by people with Parkinson’s disease that negatively impact their speech intelligibility. Yunjung also directs the FSU Motor Speech Laboratory.
