Pamela Souza, the laboratory director, received her B.S. from the University of Massachusetts at Amherst and her M.S. and PhD degrees in Audiology from Syracuse University. She is a professor and current chair of the Department of Communication Sciences and Disorders. She directs a longstanding research program in effects of hearing aids and hearing assistive technology, particularly for older listeners. Her research and clinical interests include use of signal-processing amplification which affects acoustic speech cues, how those changes interact with listener age and cognitive status, and how research findings in this area can direct clinical practice. She is a licensed clinical audiologist with special interest in working with patients who have severe hearing loss, or who have previously not been successful with hearing aids. Dr. Souza is a Fellow of the American Speech-Language-Hearing Association. Her work is supported by the National Institutes of Health (NIDCD).
Kathryn Arehart is an Associate Professor at University of Colorado. Her collaborations with Dr. Souza include the effects of hearing loss on pitch perception, signal-processing algorithms to improve speech-in-noise perception by persons with hearing loss, perception of sound quality, and the interactive effects of aging and hearing loss on speech perception.
Greg Ellis is a postdoctoral research fellow working with Dr. Pamela Souza in the Hearing Aid Laboratory at Northwestern University. He received his Ph.D. in Experimental Psychology from the University of Louisville, where he worked with Dr. Pavel Zahorik. His research interests revolve around perceptual aspects of reverberation and the effects of reverberation on tasks like speech understanding. He is generally interested in improving the outcomes of listeners with hearing impairment in reverberant environments.
Nathan Fishpaugh is completing a bachelor’s degree in computer information technology. He has experience with a range of hardware and software applications, including Qualtrics. His projects in the lab include technical support and acoustic analysis.
Frederick (Erick) Gallun is an associate professor in the Department of Otolaryngology, Oregon Health and Sciences University. Dr. Gallun’s interests include the role of non-energetic (‘informational’) masking and memory processes on the ability of listeners across the age span to make multiple simultaneous or sequential judgments in various domains (intensity, location, speech); the influences of age and hearing loss on binaural sensitivity, binaural interference, and binaural and monaural temporal integration; amplitude-modulation sensitivity and its role in speech intelligibility and interactions with compression in hearing aids; and the potential impacts of cognitive impairment on auditory tasks.
Kendra Marks, the research coordinator for the hearing aid lab, received her B.A. in Linguistics from Oakland University and her Au.D. from Northwestern University. Kendra has worked in private practice assessing hearing loss, fitting hearing aids, and programming cochlear implants. She also completed a research fellowship at the University of Michigan. Her research interests include how to best optimize hearing aid settings for an individual’s hearing loss and cognitive function.
Christopher Norwood is a 2nd year student in the Northwestern University AuD program. Chris studied Human Biology at Pitzer College in Claremont, CA. His current interests include the effects of cognition and aging on speech perception and the underlying mechanisms, including cognition, that result in individual differences in outcomes.
Melissa Yuen is an undergraduate student studying Communication Science and Disorders. Her research interests include understanding ways to optimize hearing aid and cochlear implant technologies, exploring the effects of cognition and aging on speech perception, and improving conditions for individuals with hearing loss. She is interested in pursuing her AuD in the future.
