Currently my research focuses on tinnitus, the phantom perception of a sound for which there is presently no cure or effective treatment. One of the biggest problems is that there is no objective diagnostic test for tinnitus. My postdoctoral research is laying the groundwork to develop one, which is based upon gap detection (can tinnitus “fill-in” the gap?).
“Hidden” Hearing Loss
I’m also interested in the relationship of tinnitus and hearing loss. Although most cases of tinnitus are associated with hearing loss detected by standard clinical measures, there are some individuals who nonetheless experience chronic tinnitus without detectable hearing loss. I am trying to understand these cases by uncovering possible “hidden” hearing pathology insensitive to standard clinical tests that relate specifically to the development of tinnitus. To achieve this, I combine behavioural methods, electrophysiological recordings, computational models, and machine learning methods.
Auditory Prediction, Timing, and Action
As a side interest I research the brain correlates of predictive timing and mental hierarchies of time. The neural substrates that permit a listener to anticipate auditory events in time may be reliant on linkages between auditory and motor regions that are activated even when there is no overt movement. With Fiona Manning, we are probing if the entrainment of neural activity to sound predicts sensorimotor synchronization to a beat.
Music Perception and Cognition
In a previous life I explored emotions and music. Please see publications for more information.
