Research Interests

Hyunju Chung is an Assistant Professor in the Department of Communication Sciences and Disorders at LSU and the director of the LSU Child Speech Lab. Her main research interests are on the areas of phonological acquisition, speech acoustics, and speech sound disorders. Especially, her research focuses on 1) examining speech produced by children with and without speech sound disorders (SSDs) and 2) characterizing cross-linguistic differences in the speech of children and adults.
