Director: Anthony T. Caca

Dr. Anthony T. Cacace, Professor and Director of the Hearing Science Laboratory, conducts audiological/neuroscience research and is an expert in the areas of central auditory processing disorder (CAPD), tinnitus, and novel methodologies for assessment of hearing loss, vestibular disorders, and brain-related dysfunctions. He has published a new book in 2016 entitled, “Scientific Foundations of Audiology: Perspectives from Physics, Biology, Modeling, and Medicine” with colleagues Drs. Emile de Kleine, Avril Genene Holt, & Pim vanDijk. It covers advanced topics pertinent to audiology and hearing science with the underlying premise that the audiologist is the translational interface between basic science and clinical concerns and represents the best person to apply scientific breakthroughs in molecular biology, genetics, medicine, engineering, neuroimaging, etc., and implement them in the clinic to advance the field. He is also interested in developing the use of hearing simulators and contemporary vestibular testing for student education and research. In this context, he has received over $64,000 in CLAS Omnibus grants over the last four years to move forward with these initiatives. 

Dr. Cacace is currently working on several NIH and VA-funded research grants focusing on (1) vagus nerve stimulation and tinnitus suppression based on a targeted neuroplasticity framework in humans, (2) in applying novel theranostic approaches to identify and treat tinnitus using functionalized nanoparticles, (3) in developing other effective strategies for tinnitus diagnosis and treatment in animal models, and (4) in assessing the effects of blast exposure and noise on vestibular system function in humans and animals.  

Dr. Cacace teaches the Au.D. research methods sequence and the course “Medical Issues: Tinnitus and Central Auditory Processing



Director: Jinsheng Zhang, Ph.D.

Dr. Jinsheng Zhang, Professor, is jointly appointed in our CSD department and in the Department of Otolaryngology in the WSU School of Medicine. Dr. Zhang’s current work includes several funded research projects, including “Targeting TNF-Alpha for Treatment of Blast-Induced Tinnitus” funded by the U.S. Department of Defense. He is leading an NIH-funded R21 from NIDCD entitled, “Cochlear Electrical Stimulation to Suppress Tinnitus in Rats.” He is collaborating on a project funded by the U.S. Department of Defense entitled, “Developing TNF-Alpha-Mediated Treatment for Blast-Induced Tinnitus.” He currently leads a project funded by the Martha Entenmann Tinnitus Research Center Inc. to “Drug development for treating noise-induced subjective tinnitus of the severe disabling type.”

Dr. Hsieh’s research and professional interests include bilingualism and multicultural issues. As a member of the Multicultural Issues Board for the American Speech-Language-Hearing Association (ASHA), Dr. Hsieh was Chair of the awarded ‘Trailblazer’ session “Increasing Cultural Competence: Asking the Right Questions Without Trivializing Culture" at the 2015 national meeting. This year Dr. Hsieh directed student research and taught undergraduate courses in ‘Speech Science’ and the graduate course ‘Neuroscience of Communication Disorders.”

Director: Margaret Greenwald, Ph.D., CCC-SLP

Dr. Margaret Greenwald studies adult acquired language disorders (aphasia) including anomia, dyslexia, dysgraphia, agnosia, and neurorehabilitation. She is working to understand factors that promote generalization of learning to functional communication contexts in stroke survivors through the project “Cognitive and Social Approaches to Aphasia Treatment.” She directs graduate student research and teaches graduate courses in ‘Acquired Linguistic & Cognitive Disorders in Adults,’ ‘Research Methods in Communication Disorders,’ and Doctoral Seminars.
