Research Description:
My research aims to better understand the variability in cochlear implant (CI) outcomes. Particularly, I focus on using measures of neural plasticity (e.g. fNIRS) to measure changes at the level of the cortex that occur during hearing loss and following implantation. I am also interested in seeing how genetic information can be used to help predict these differences, in plasticity and outcomes, for CI candidates.
