Research Statement

Dr. Lutfi's research focuses on human auditory perception. He is particularly interested in how one's ability to detect and recognize complex sounds is affected by both lawful and random variation in sound, as occurs in nature. A goal of his research is the development of mathematical models for predicting detection and recognition performance under various conditions of signal uncertainty. Bob also conducts research on the perception of complex sounds by hearing-impaired listeners, and on the auditory abilities of children.
