Research Interests: Speech perception by hearing-impaired listeners, especially cochlear implant users; perception of talker-specific properties of speech by cochlear implant users, perception of suprasegmental speech characteristics and its relation to learning words; psychoacoustic abilities of cochlear implant users and of persons with unilateral hearing loss.

Dr. Uchanski collaborates closely with Drs. Lisa S. Davidson, Jill B. Firszt, and Johanna G. Nicholas, and with their laboratories.
