The primary focus of my research is to examine the perceptual, cognitive, and audiological factors influencing speech and language outcomes in children with cochlear implants (CIs) and hearing aids (HAs). The foundation for this multidisciplinary approach is providing optimal audibility through sensory devices (HAs and CIs). My experience as a clinical pediatric audiologist motivates me to address key clinical questions with evidence based research.

Research Projects

The Effects of Early Acoustic Hearing for Pediatric Cochlear Implant Recipients

The overall goal of this research program is to identify a critical period in infancy/early childhood during which acoustic experience with a hearing aid/s facilitates language development following cochlear implantation.

Audibility, Sensory Aids and Cognition as Factors in Children’s Speech Perception

The overall goal of this research program is to specify how perceptual and cognitive abilities interact to determine relative benefits of sensory devices for children with moderate to profound sensorineural hearing loss.

Evaluating Verbal and Visuospatial Working Memory in Children with Cochlear Implants

The principal goal of this research program is to examine the effects of auditory deprivation on different measures of working memory including verbal and visuo-spatial working memory in children using cochlear implants.

The Effects of Hearing Aid Frequency Response for Bimodal Pediatric CI users

The overall goal of this research program is to examine the effects of the hearing aid fitting on the benefits of bimodal devices for children.
