Global Center for Hearing and Speech Research

The Global Center for Hearing & Speech Research is a focal point of hearing, speech and deafness research, including ties with the Departments of Communication Sciences & Disorders, Chemical & Biomedical Engineering, and School of Aging Studies. The Center clinicians and researchers have diverse backgrounds and expertise at multiple levels: research scientists, visiting scholars, postdoctoral fellows, research audiologists, technicians, and students. Through the Center's faculty and trainees, affiliations and collaborations involving the Center represent distinct and varied professional disciplines within the University, across the country, and internationally.


In addition to the four GCHSR Directors, the following USF Faculty serve as Core Members.

Dr. Ann Eddins earned a B.S. in Communication Disorders from Northwestern University, M.A. in Audiology from the University of California at Santa Barbara, Ph.D. in Auditory Physiology from SUNY University at Buffalo, an M.S. in Business Administration/Medical Management and an M.B.A. both from the University of Rochester, Simon School of Business. She started her academic career as a post-doctoral fellow in Neuroscience at the University of Florida followed by faculty positions in Audiology /Hearing Science at Indiana University and SUNY University at Buffalo. She subsequently served as the Director of Audiology at the University of Rochester Medical Center before joining the University of South Florida in 2010. Dr. Eddins' research and clinical interests are aimed at understanding the neural correlates of auditory perception in normal and impaired hearing, and the potential for neural plasticity following intervention. Her work has incorporated both human and animal models using a range of basic science and clinically applied techniques including single- and multi-neuron measures, evoked and event-related potential measures, neuroimaging and psychophysics. Current projects are focused on the identification of neural signatures, or biomarkers, of perceptual changes in binaural processing with age and hearing loss, changes in complex spectro-temporal processing with age and hearing loss, and the effects of intervention on such biomarkers. In addition to her interests in basic science, Dr. Eddins also has expertise in small business development and health care organizational management.
