SLHS Faculty by Research Area

Developmental Disorders

SLHS faculty have long been leaders in the scientific study of developmental disorders of speech and language. Research extends beyond traditional study of diagnosis and treatment to discovery of underlying processes for both normative and disordered performance. Faculty bring especially rich expertise in Autism Spectrum Disorder, Speech Disorders, and Language Disorders.

Hearing Science

At Purdue, one of the largest groups of hearing scientists in the world study hearing, both healthy and impaired, with a broad arsenal of methods including neurophysiology & electrophysiology, psychophysics, and computational modeling. Research extends from early development and plasticity through aging with emphases on hidden hearing loss and speech perception.

Neurological & Degenerative Disorders

Many of the most significant advances in understanding communicative and related disorders arise from a richer understanding of underlying neurological and physiological processes. This is especially true for research in aphasia, dysphagia (swallowing), Parkinson’s Disease, and voice disorders.
