Lori-Ann Ferraro, Ph.D., CCC-SLP
Dr. Lori-Ann Ferraro’s research interests include the Scholarship of Teaching and Learning (in both didactic and clinical learning and their connections to clinical practice), collaborative learning, administration in clinical education, and competency-based education. Her research interests are two-fold: 1. examining novel and innovative models of clinical education that also provide efficacious learning experiences for students and how to help students construct the connections between theoretical constructs taught in didactic settings and their clinical application and 2. discovering factors that impact SLPs’ willingness to become a clinical instructor, which spans clinical placement shortages.

Sabrina Horvath, Ph.D., CCC-SLP
Dr. Sabrina Horvath’s research focuses on how children develop language during the preschool years. She is particularly interested in whether children who have or who are at risk for developing language disorder, such as late talkers, use the same strategies to learn language as typically developing toddlers. Long-term, this research will be used to support earlier identification of and more efficacious interventions for children with language disorder.

Adult Medical Swallowing and Language Research Lab
About Our Lab
What do we do?
The Adult Medical Swallowing and Language Research Lab (AMSL) at the Medical University of South Carolina focuses on advancing research and providing education in swallowing disorders (dysphagia) and language impairments (aphasia).Our Mission
Our mission is to improve understanding, diagnosis, and treatment for individuals affected by dysphagia and/or aphasia. Through research, education, and collaborations, we aim to enhance patient care and quality of life.Our work is driven by curiosity, compassion, and a commitment to translating research discoveries into real-world clinical impact. We believe that research should directly inform patient care — and that collaboration between researchers, clinicians, and patients is essential for meaningful progress.
Our Vision
We envision a future where every person with a swallowing or language disorder can access innovative, evidence-based care that meets their unique needs.What is Aphasia?
Aphasia is a language disorder caused by damage to the brain’s language centers, often caused by stroke or head injury. It affects a person’s ability to understand, speak, read, or write. Aphasia can range from mild communication difficulties to severe impairments. Rehabilitation efforts focus on helping individuals regain their language skills through therapies and innovative techniques.What is Dysphagia?
Dysphagia refers to difficulty swallowing, which can impact the ability to safely move food or liquids from the mouth to the stomach. It may result from conditions such as stroke, Parkinson’s disease, or head and neck cancer. Dysphagia can lead to complications like malnutrition, aspiration pneumonia, or choking. Our lab investigates the underlying mechanisms of dysphagia and develops strategies for effective management.Team

Terry Hopkins-Rossabi, Ph.D., CCC-SLP, BCS-S
Dr. Terry Hopkins-Rossabi brings over 30 years of clinical experience in medical speech-language pathology to her research on swallowing disorders (dysphagia). Her primary focus thus far in the MUSC SLP program has been as an instructor in Adult Swallowing, Cognitive Communication Disorders in Adults, Trach and Ventilatory Patients, Assessment, Intro to Research, and Counseling. Her research projects have focused primarily on adult swallowing disorders and the importance of instrumental evaluation of swallowing. These projects have resulted in presentations, including SLP master’s students at national and state conferences as well as a publication in the Dysphagia journal. She is a national leader in dysphagia education, clinical care, and research, with a special interest in adult swallowing. When not teaching or involved in projects in the lab, Dr. Rossabi will be hiking, kayaking, skiing, or spending time with her husband, two children, and their partners.

Research Studies Conducted in the AMSL Lab
Neuroanatomical correlates of dysphagia after stroke
We investigate how stroke lesions are associated with swallowing impairments to identify the neural circuitry that supports swallowing function after stroke. Beyond lesion-related damage, we are also interested in understanding how age-related neuroanatomical changes contribute to post-stroke dysphagia. Our overarching goal is to establish a theoretical framework for the neural control of swallowing after stroke. Through this work, we aim to improve early-stage risk prediction and patient counseling following stroke. Ultimately, our findings may help identify neuroanatomical targets for intervention and support efforts to prevent complications of dysphagia.Dr. Wilmskoetter has received funding from the National Institutes of Health to support this line of research.

Therapy for people with aphasia after stroke
In collaboration with the Center for the Study of Aphasia Recovery (C-STAR) at the University of South Carolina, we investigate how individuals recover from aphasia following stroke. As part of this work, we are conducting clinical trials to evaluate how aphasia therapy can enhance communication abilities and improve the quality of life for people with aphasia. Our goal is to deepen our understanding of how to personalize aphasia treatment based on each individual's unique profile, ultimately optimizing recovery outcomes.Resources for Patients and Families
We provide resources designed to support patients and caregivers navigating aphasia and dysphagia.
Support Groups:
Connect with others facing similar challenges.
- Charleston Communication Connection (CCC) is a group for adults with acquired communication disorders like aphasia or apraxia. The group meets monthly for a variety of educational and therapeutic activities as well as conversation and support. Past events have included watching and discussing a documentary on aphasia, hearing from a 911 operator and police officer about access to emergency services, and participating in an art therapy session. Speech-language pathology graduate students from MUSC also join the group each month to learn from the group members. The group meets the last Friday of each month (January through October) from 2:30pm-3:30pm in the Garden Room at MUSC Midtown- 1600 Midtown Avenue, 29464. For more information, contact Stephanie Cute at cute@musc.edu.
Clinical Trials:
We are actively recruiting participants for our ongoing treatment study “TERRA.”
The purpose of this Telerehabilitation for Aphasia (TERRA) research study is to assess the effectiveness of telehealth aphasia therapy visits compared to aphasia therapy administered in person at our clinic.
Study participants will:
Complete several tests that assess your speech and language abilities.
Receive a magnetic resonance image (MRI).
Receive a total of 30 speech therapy sessions, randomly assigned to be delivered either in-clinic or via teletherapy.
You may be eligible to participate if you:
- Have a left hemisphere ischemic or hemorrhagic stroke at least 12 months ago
- Are between 21 and 80 years of age
- Are compatible with MRI (e.g., no metal implants, not claustrophobic)
- Are not currently enrolled in or receiving speech-language therapy provided by a licensed therapist
