She is interested in behavioral flexibility, with a focus on differences between carnivore species, wild vs. captive populations and the relationship between inhibition and innovation.
Jacob Pappas

Jacob is interested in comparative and evolutionary psychology, particularly in examining the functions of animal cognition and what that might suggest for analogous traits in humans, in regard to their evolutionary function. A particular subject of interest is how human domestication has shaped the cognitive state of dogs versus non-domesticated canids.
Anne Sullivan

Anne is an experienced animal trainer who is interested in how animals learn through mimicry and other learning processes. She is also interested in retention and welfare.
Jordyn Truax

Jordyn's research interests include social behavior and cognition in nonhuman animals. Specifically, she is interested in cooperation, prosocial behavior, altruism, and the motivations behind these behaviors.
Joy Vincent

Joy’s research broadly focuses around comparative cognition in exotic species, such as elephants and warthogs. Through the study of social behaviors and dynamics—particularly, the interplay of competition and cooperation—she hopes to better inform practices that promote the conservation and welfare of both captive and wild animals.

Robert Hutton (MS 2019)

Robbie's primary research interests include empathy and social cognition in both humans and nonhuman animals. He seeks ultimately to carry out research incorporating both comparative and social/personality principles from an evolutionary perspective. He is also interested in narcissism, religiosity, prosociality, and many, many other topics.

Stephanie Jett (PhD 2014)

Stephanie is interested in: human and animal cognition,
evolution of language/communication, concept formation, memory, and social and physical cognition.
She is currently working with birds of prey (hawks, eagles, and owls) and carrion birds, (vultures and crows) on spatial memory, tool use, numerosity, and social
cognition tasks. She also conducts research with domestic dogs, rodents, and primates. Her dissertation focused on how language complexity, sex and levels of abstraction affects natural and emotion concept formation. Stephanie is now an assistant professor at Georgia College and State University in Milledgeville, GA.

Zoe Johnson-Ulrich (PhD 2017)

Zoe is interested in comparative cognition, specifically physical cognition (e.g. cognition about physical support, connectedness, object permanence, or physical causality), and also empathy and predator/prey or interspecific communication. Her dissertation focused on behavioral flexibility, innovation and inhibition in carnivores. She is most interested in animals that humans routinely interact with, such as bears, dogs, and horses.

Silvia Oriani
Audrey Robeson MS 2018

Audrey is interested in animal cognition and comparative psychology. Her main focus is on animals’ strategies to overcome emotional stressors, how animal strategies differ from the strategies of humans, in particular that of those on the autism spectrum. In addition, she is looking to explore how humans can manipulate environments to increase the welfare of both captive non-human animals and endangered animals outside of captivity with the hopes of increasing reproductive success and increasing quality of life.
Audrey is now working as a behavioral specialist.
