Biography
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 was he primary instructor for Psych 330: Animal Behavior Lab (2012-2013). He graduated with a Ph.D. in Psychology (Animal Behavior) in the Spring 2013.

Research Interests
Peter's research interests are in sensory neurophysiology in the context of natural behaviors. His research examined 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 used neuroanatomical methods to investigate the potential mechanism(s) responsible for the previously observed ontogenetic plasticity of saccular afferent senstivity in the plainfin midshipman.
