Cetacean
sensory and perceptual processes
My research interests focus on the sensory and perceptual processes
of dolphins and small whales. Past research has focused on taste
reception, vision, hearing and echolocation of toothed whales and
dolphins. Currently conducting research on hearing (sound localization,
low frequency audiometrics, evoked auditory potential measurements
as a way to study hearing in large whales, examining hearing while
animals echolocate), echolocation (determining acoustic processes
of echolocation via phantom echo experiments, effects of noise on
dolphins, modeling discrimination abilities) with further interest
in aiding stranded animals and may be conducting future studies
on vision and taste reception.
