Research Interests:
My research is predominately in the area of human auditory information processing, with an emphasis on binaural hearing and sound localization. At the center of my research program is the question of how the auditory system, when operating in complex, multisource acoustic environments, "parses" the frequency components that are present to determine sources or form auditory objects. My research is particularly aimed at examining the role that spatial hearing plays in segregating concurrent acoustic stimuli, although I have also examined the manner in which binaural cues interact with other variables that promote segregation of sources. My goal is to develop a set of objective psychophysical procedures that allows one to characterize the tendency of listeners to analytically/synthetically process information across different stimulus dimensions.
