  • National Science Foundation Postd-Doctoral Fellow: University of California at San Diego 1970-1971
  • Ph.D. Experimental Psychology, Indiana University 1970
  • B.A. Psychology; minor: Mathematics, The Colorado College 1966 
Research Interests: 

Auditory perception and psychoacoustics in areas of pitch perception, sound localization including localizing sounds in reverberant environments and virtual auditory environments, processing sounds with modulated waveforms, sound source determination and segregation, and computational modeling with respect to time-based neural models of complex sounds. Animal psychophysics in areas related to pitch perception and processing modulated sounds. Applications of this work to societal issues such as noise pollution (on land and in the seas), hearing impairment and hearing aids, and people-machine interactions.
