Frits van Brenk works as an external collaborator in the Motor Speech Disorders Laboratory in the Department of Communicative Disorders and Sciences at the State University of New York at Buffalo.

He previously worked as postdoctoral researcher in the Motor Speech Disorders Laboratory, and as lecturer in the Linguistics program at Utrecht University in the Netherlands, where he also received his BA and Research MA in Linguistics. He received his PhD in Speech and Language Therapy at the University of Strathclyde in Scotland.

His research focuses on the assessment of speech of neurotypical speakers and speakers with neurological disorders, in particular speech characteristics of persons with dysarthria and apraxia of speech. Using different perceptual, acoustic, and kinematic experimental methodologies, he hopes to contribute to the body of knowledge on motor speech disorders with a view to improve diagnostic measures that may aid assessment and broadening of clinical treatment options.
