Education: 

B.S., MIT, 1986 (Electrical Engineering); M.S. Northwestern, 1993 (Electrical Engineering); Ph.D., Northwestern, 1997 (Electrical Engineering); M.S., Univ. Mass., 2004 (Communication Disorders); CCC-A, American Speech-Language Hearing Association, 2006.

Area(s) of Specialization: 

Speech intelligibility; Signal processing; Hearing aids; Cochlear implants; Electroacoustics

Research Description: 

My research is concerned with modeling and predicting speech intelligibility for hearing-impaired subjects listening in adverse conditions.  Insights from this work will inform the design and usage of hearing aids, cochlear implants, and other assistive listening devices.
