Bio and Expertise

Sarah E. Wallace PhD, CCC-SLP is an Associate Professor and Program Director for the Adult Language and Cognition clinic in the Speech-Language Pathology Department at Duquesne University in Pittsburgh, Pennsylvania. Dr. Wallace also directs the Communication and Cognition Lab ( Dr. Wallace is a certified speech-language pathologist with clinical experience providing services to individuals with acquired communication disorders. At Duquesne University she teaches the following graduate courses: Aphasia in Adults, Neurocognitive Communication Disorders, Augmentative and Alternative Communication with Lab, and Capstone in Evidence-Based Practice. She also provides multiple guest lectures within the Health Science Departments focused on augmentative and alternative communication and interprofessional roles and responsibilities. Dr. Wallace regularly leads Interprofessional Education learning opportunities for Duquesne University students. In addition to her classroom and clinic teaching responsibilities, Dr. Wallace often mentors student research projects.
Dr. Wallace proudly serves as Co-Editor for Topics in Language Disorders ( and Editor for the Journal of Speech, Language, and Hearing Research ( She also serves in various leadership positions within the Academy of Neurologic Communication Disorders and Sciences (, the American Speech-Language-Hearing Association (, and Aphasia Access (

Dr. Wallace conducts clinical research aimed at improving the quality of life for individuals with communication impairments following traumatic brain injury and aphasia resulting from stroke. Her active, interdisciplinary research program is focused on the following broad objectives:
1. Develop compensatory strategies that support reading and auditory comprehension in people with aphasia
2. Investigate home practice programs for people with neurological disorders
3. Explore methods of integrating technology into provision of clinical services for individuals with neurogenic communication disorders
4. Develop a multimodal intervention program to assist people with neurogenic communication disorders to successful resolve communication breakdowns.
5. Explore modifications that increase generalization resulting from semantic feature interventions implemented with people with aphasia.
6. Investigate strategies for implementing interprofessional education activities that increase collaborative practices used by clinicians with a particular emphasis on the learning outcomes from speech-language pathology students.
