Translating thoughts into spoken words is a seemingly effortless ability, one easily taken for granted, yet speech production is a fascinating and remarkably complex process. My research focuses on central and peripheral correlates of speech production, and how breakdowns in these intricate networks contribute to speech disorders such as stuttering and dysarthria.
I joined the Department of Communicative Sciences and Disorders in the College of Communication Arts and Sciences as an Assistant Professor in August 2018. I received my B.S. and M.S. in Speech-Language Pathology and Ph.D. in Interdisciplinary Neuroscience at Purdue University.
Developmental trajectories to stuttering persistence and recovery
Project Narrative: Stuttering affects 70 million people worldwide and often has lifelong adverse consequences. In this project, we examine the mechanisms underlying stuttering persistence and recovery in preschool-aged children. We will use a comprehensive, multilevel approach to examine the development of neural, physiological, and behavioral mechanisms associated with different stuttering outcomes. This research is consistent with the mission of NIH in that our ultimate goal is to translate scientific discoveries about how stuttering develops in young children into advances in diagnostic and intervention approaches.
