Publications, Presentations, & Advocacy
The SNAP Lab is constantly engaging with students, clinicians, researchers, and the community! On this page, you will find a selection of publications and presentations, as well as advocacy initiatives presented before legislative bodies. Although our research is focused on stuttering and other neurodevelopmental disorders, out overarching goal is to elevate the human condition through knowledge, training, and experience.
