Dr. Griffin is a medical speech-language pathologist with clinical and research interests in the neural mechanisms of normal and disordered swallowing in adults. She studies methods of augmenting traditional dysphagia rehabilitation using electrical and sensory stimulation as well as ways to improve swallowing evaluation procedures. She has published her work in several peer-reviewed journals, including DysphagiaAmerican Journal of Speech-Language Pathology, and Experimental Brain Research.

Dr. Griffin teaches graduate coursework in neurogenic communication disorders and dysphagia. She supplements course materials with evidence-based practice techniques and examples from her clinical experiences across the continuum of care. Students interested in gaining research experience with adult swallowing disorders are encouraged to contact the EATS Lab.
