Listening with
cochlear implants:
At the MRC Cognition and Brain Sciences Unit in
Cambridge in Bob Carlyon's group, I worked on two main topics: dip listening and temporal coding
of pitch. In Ruth Litovsky's lab at UW-Madison, my work was focused on bilateral cochlear implant listeners. These project have utilized direct stimulation via research processors, stimulation via clinical processors, and simulation with vocoded sounds.
- How is temporal pitch information encoded and combined
across electrodes?
- How does the fidelity of ITDs versus ILDs affect spatial release from masking.
- How are spatial cues combined across pairs of electrodes?
