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 at Northwestern University. She directs a longstanding research program in effects of hearing aids, 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. Dr. Souza is a Fellow of the American Speech-Language-Hearing Association and serves on the Psychoacoustic and Perception Technical Committee of the Acoustical Society of America. 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 will be awarded his Ph.D. in Experimental Psychology from the University of Louisville in August 2018 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.
Frederick (Erick) Gallun is a staff investigator at the National Center for Rehabilitative Auditory Research and 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.
Amanda Mueller is a first-year Au.D student at Northwestern University. She received her B.S. in Speech, Language, and Hearing Sciences from Purdue University. Her research interests include vestibular disorders, frequency lowering in hearing aids, and hearing conservation.
Patrick Zacher received his bachelor’s degree in Civil Engineering from the University of Illinois at Urbana-Champaign and subsequently served in the Navy. He is currently a post-baccalaureate student in the Pre-Clinical Psychology program. His research interests include cognition and hearing disorders in aging populations.
