Inyong Choi CV

Research focus
Dr. Inyong Choi and the Human Auditory Neuroscience Group conduct two parallel research programs: 1) A basic auditory-cognition research line that investigates neural mechanisms normal hearing listeners use to understand speech-in-background noise and 2) a more clinical line of research where we try to identify neural markers and treatment options that will improve speech-in-noise processing by individuals with impaired hearing systems.
