Research Description:

My work focuses on improving outcomes for children and adults with cochlear implants both in the clinic and the research lab. As a clinical audiologist, I understand the need for improving outcomes for patients with hearing loss to improve communication and quality of life. As a hearing scientist, I am interested in clinically translational research focused on improving outcomes through a personalized medicine approach including cochlear implant selection, electrode placement, programming parameters, and aural (re)habilitation.
