I am a cognitive neuroscientist with expertise in psychoacoustics and electrophysiology, and I have primarily led research on the behavioral and neural mechanisms associated with sensorineural hearing loss across the adult lifespan. My research interests are in cognitive aging, speech perception, spatial attention, and emerging technologies in medical and commercial hearing instruments.

Understanding aided speech perception in noise

Hearing aids are designed to improve communication by reducing gain at spatial locations away from relevant speech, but not all listeners benefit from this imprecise strategy. In this study, we investigate the effects of directional processing on speech perception in noise using a three-pronged approach that systematically controls hearing aid digital signal processing, assays relevant behavioral measures, and discovers the neural processes affected by aided listening. The goal of this study is to launch a comprehensive framework for hearing aid evaluation and development grounded in established models of hearing and neuroscience.

Analysis and Development Supporting New Generations of Binaural Hearing Systems

This project involves evaluation of signal processing algorithms in a hierarchy of complex listening environments that are designed to challenge the environmental classification and binaural hearing systems in current state-of-the art hearing instruments.

Industry Contract - Bose Corp

Sound Quality Comparison of Bose Hearphones and Premium Hearing Aids

The goal of this project are to compare the sound quality of Bose Hearphones to a high-end, behind-the-ear hearing aid when those two devices are fit using manufacturer’s recommendations and clinical best practices, including audiologically-appropriate venting for the hearing aid fitting.

Behavioral and Cortical Signatures of Reduced Auditory Spatial Tuning with Age

This project investigated sensory and cognitive changes to binaural processing with age. Using a combination of behavioral and electrophysiological techniques, results provided the empirical and theoretical bases to guide appropriate remediation methods.

Aging Auditory System: Presbycusis and its Neural Bases

Multidisciplinary determination and characterization of the perceptual, neural and molecular bases of age-related hearing loss in humans and animal models. The foci of Project 1 are on discovery of the nature and magnitude of age-related changes in (1) central auditory plasticity and the ability to use residual plasticity to ameliorate symptoms of hearing loss and (2) spatial-temporal processing.

A Psychoacoustic Approach to Dysphonic Voice Quality & Pediatric dysphonia: Multidisciplinary advances to improve voice quality outcomes Perception

The goal of these studies are to better define indices of pathological voice by systematically manipulating specific acoustic characteristics known to influence voice quality judgments and to evaluate those manipulations on listener judgments and discrimination measures as well as via computational models of auditory processing.
