I have extensive training in clinical medicine, auditory electrophysiology and psychoacoustics. My long-term research goals are to better understand neurophysiological mechanisms of auditory-perception deficits in human listeners, and to identify biomarkers for clinical diagnosis and treatment selection. In the last 20 years, I have investigated neural encoding and auditory processing of electrical stimulation and their association with auditory perception in CI and auditory brainstem implant users. My past work successfully established the application of auditory event-related potentials in assessing cortical neural encoding of auditory input and its correlation with auditory perception in listeners with acoustic or electrical hearing. My recent work 1) developed an approach for measuring the electrically evoked compound action potential (eCAP) in children with severe inner ear malformations, 2) revealed that the eCAP can be used to assess cochlear nerve survival, the quality of the electrode-neuron interface and how well the cochlear nerve encodes and processes electrical stimulation, and 3) established the importance of the functional status of the cochlear nerve for understanding speech in complex listening conditions.
