Peter received a B.S. in Zoology from Brigham Young University (2005).
As an undergraduate, Peter did research in the lab of Dr. R. Paul Evans
using recombinant DNA techniques to determine to what extent speciation
was occurring between two populations of Yellowstone trout. Since entering
the Sisneros Lab in the Fall of 2006, Peter has been involved in a wide
range of projects including the reproductive biology of plainfin midshipman,
sound source localization in teleost fishes, hearing sensitivity of the
Lusitanian toadfish, as well as his own dissertation research on the ontogeny
of hearing in the midshipman. Peter was awarded a NIH predoctoral Auditory
Neuroscience Training Fellowship from 2007-2010 and he is currently the
primary instructor for Psych 330: Animal Behavior Lab (staff.washington.edu/pwa2/Home.html).
interests are in sensory neurophysiology in the context of natural behaviors.
His current research examines the ontogeny of hearing sensitivity in the
plainfin midshipman using both electrical physiology (recording evoked
saccular potentials) and behavioral techniques (startle-like responses)
to determine the behavioral onset of hearing and hearing sensitivity throughout
development. Peter plans to use neuroanatomical methods to investigate
the potential mechanism(s) responsible for the previously observed ontogenetic
plasticity of saccular afferent senstivity in the plainfin midshipman.
