Summary of Research Interests:

My laboratory investigates the perception of complex acoustic stimuli in birds and small mammals using both behavioral and physiological techniques. These stimuli include speech sounds, binaural stimuli, and stimuli that produce auditory illusions. Demonstrations of auditory illusions in animals are extremely important for understanding auditory functioning in realistic environments in both normal and hearing-impaired populations. I am interested in determining whether birds exhibit certain illusions and what the underlying neural correlates are to these illusions – that is, where the disconnect occurs between the presented stimulus and the perceived stimulus.
