About Charles Ellis

Charles Ellis Jr., received his Bachelor of Science and Master’s degree from The University of Georgia, Athens, GA. and Doctor of Philosophy degree from the University of Florida, Gainesville, FL. Dr. Ellis’ academic concentration focuses on adult neurogenic disorders and he teaches courses related to aphasia and cognitive disorders. His research is designed to understand outcomes associated with adult neurologically based disorders of communication and factors that contribute to the lack of equity in service provision and outcome disparities that exist among African Americans and other underrepresented minority groups. Dr. Ellis has authored peer-reviewed journals articles and book chapters related to neurological disorders and health disparities and minority health issues.

Research Profile

Dr. Ellis is engaged in research designed to understand outcomes associated with adult neurologically based disorders of communication and factors that contribute to the lack of equity in service provision and outcome disparities that exist among some population groups.

Research projects emphasize:

1. Outcomes associated with neurologically based disorders of communication.

2. Economic issues associated with neurologically-based disorders of communication disorders; specifically the costs and cost-effectiveness of speech-language pathology interventions.

3. Health-related disparities that occur among those with neurological disorders that are not specifically due to race or ethnicity but indirectly associated factors such as access to care, availability of care, socioeconomic status (SES), insurance, belief systems and resource utilization.
