Executive Director

Andrew Oxenham headshot

Dr. Andrew Oxenham is a Distinguished McKnight University Professor in the Departments of Psychology and Otolaryngology. He is an expert in human auditory perception and neuroscience, bridging both the basic and applied branches of auditory science. His research has been continuously funded by the National Institutes of Health (NIH) since 1998 and he has authored over 200 journal articles and book chapters. His focus has been on the perceptual consequences of hearing loss and on understanding and improving sound perception through cochlear implants. He is a past winner of the Troland Award from the National Academy of Sciences and of the R. Bruce Lindsay Award from the Acoustical Society of America.

Scientific Co-Directors

Gordon Legge headshot

Dr. Gordon Legge is a Distinguished McKnight University Professor and former Chair of the University of Minnesota's Department of Psychology. He is a leading scientist in vision research and was the recent winner of the Helen Keller prize for vision research from the Helen Keller Foundation and the BrightFocus Foundation. Dr. Legge's research deals with visual perception and cognition. Currently, projects focus on the roles of vision in reading, object recognition, and spatial navigation. In all of these areas, there is a special focus on the problems encountered by people with low vision. The lab has been widely recognized for applying the principles and methods of basic visual science to explain the difficulties encountered by people with low vision. Other areas of include studies of binocular vision (including stereopsis) and contrast coding.

Peggy Nelson headshot

Dr. Peggy Nelson is a Dean's Medal Professor and former Chair of the Department of Speech-Language-Hearing Sciences (SLHS). Her work bridges auditory psychophysics, speech perception, and sensory aids. She has had NIH funding since 1992, completing a K08 mentored scientist award, an R03 small grant, and two different R01 research grants. Her work originally focused on the psychophysics of hearing loss, but has moved into translational work on sensory aids, both hearing aids and cochlear implants. She has had a number of subcontract awards from small business grants, which have led to fruitful collaborations between her students and local industries. She has mentored a number of PhD and AuD students, as well as post-doctoral fellows. She has served as a mentor for other NIH K08 and K23 awards. She has also served as Chair of the Department of Speech-Language-Hearing Sciences, with her current term ending in Summer, 2015.
