Investigators & Laboratories


Monita Chatterjee, Ph.D., Perception of Complex Stimuli & Cochlear Implants

Work in this laboratory focuses on understanding the factors that influence the perception of complex sounds, including speech, by patients with cochlear implants.

​Shuman He, M.D., Ph.D., Human Auditory Electrophysiology

This research program aims to better understand neural encoding of sounds at the peripheral and the central auditory system in hearing impaired listeners.

Michelle L. Hughes, Ph.D., Cochlear Implant Research

Research is concerned with the relation between objective tests of auditory-nerve function and subjective tests of perception, and whether these objective or subjective measures can be used to find better ways to program speech processors associated with cochlear implants.

Kristin Janky, Ph.D., Vestibular Assessment and Balance Disorders

The work in this laboratory is concerned with the study of vestibular disorders, including their diagnosis and treatment.

Douglas Keefe, Ph.D., Physicial Acoustics Laboratory

This research is focused on better understanding the mechanics of the middle ear and cochlea to develop better screening and diagnostic tools.”

Lori Leibold, Ph.D., Human Auditory Development

This research lab studies the development of auditory behavior in children with normal hearing and children with hearing loss, with a focus on understanding how infants and children hear and process target sounds in the presence of competing background sounds.

Dawna E. Lewis, Ph.D., Minimal Hearing Loss in Children

The primary goal of the research is to examine the impact of minimal hearing loss on a range of functional auditory and language skills that support learning.

Ryan McCreery, Ph.D., Perceptual and Cognitive Development in Children with Hearing Loss

This research program is concerned with enhancing speech and language outcomes in children with hearing loss by improving audibility based predictions of speech recognition.

Mary Pat Moeller, Ph.D., Language Development Laboratory

The goal of the research program is to examine outcomes in children with mild to severe hearing loss, and to understand factors that explain variations in subject performance. Children are seen regularly for a comprehensive battery of audiological, speech-language and psychosocial measures. In addition, child and family characteristics and the extent and nature of services the children are receiving are examined.

Stephen T. Neely, D.Sc., Communication Engineering

Research is concerned with understanding the mechanisms by which the inner ear processes sound, using empirical studies and modeling work to gain better insights into cochlear function.

Daniel Rasetshwane, Ph.D., Auditory Signal Processing

Research focuses on advanced signal-processing strategies for hearing aids and loudness perception in normal-hearing and hearing-impaired individuals.

Nicholas A. Smith, Ph.D., Perceptual Development

Research focuses on behavioral methods to study the development of infants’ perceptual and cognitive processing of sounds, such as speech, music, and complex tone patterns.
