Social behavior, vocal communication, and cognition of nonhuman primates in their natural habitat

Research Synopsis:

My research focuses on the social behavior, vocal communication, and cognition of animals in their natural habitats. Methods include observational sampling, tape-recording of vocalizations, playback experiments, and the collection of hormonal and genetic data from fecal samples. My goal is to clarify the differences between nonhuman primate communication and human language, to explore the adaptive value of primate social relationships, and to examine the cognitive mechanisms that underlie close social bonds. My graduate student Isaac Schamberg studies vocal communication among bonobos in the Democratic Republic of Congo (Isaac works jointly with Gotfried Hohmann at MPI Leipzig). Graduate student Emily Bray is conducting a longitudinal study of behavioral and cognitive development among puppies at The Seeing Eye Foundation in New Jersey (Emily’s work is jointly supervised by James Serpell at the Penn Vet School). Although I plan to remain active in research, I will retire at the end of academic year 2015-16 and am no longer accepting graduate students.
