Robert Gross is curious about human/non-human continuity, especially where and how the perceptions, experiences, and prosocial actions of other animals are similar and different from that of humans.  He is interested in developing the foundation of a phylogenetic tree of behavior, by studying the comparative prosocial and empathetic behaviors of mammals that serve as clues to the evolutionary history of social cognition.

Jacob Pappas

Picture
​Jacob is interested in moral and evolutionary psychology. In particular, he is interested in the role theory of mind plays in moral cognition, especially as evidenced by moral processes that operate in its absence. He is also interested in the role moral processes play in marginalization, and evolutionary theories of morality and neurodiversity.ticdiversity

Jennifer is now working  with the Center for Zoo Animal Welfare at the Detroit Zoological Society.

Eric Hoffmaster (MS 2016)

Picture

His MS thesis focused on the study of prosocial behavior in bats. He is also interested in animal welfare and how animal cognition could be applied to increase the well being of captive animals. 


Eric was recently the enrichment director for the wildlife group at Best Friends in Utah. He is now working for the National Wildlife Federation.

 Robert Hutton (MS 2019)
​

Picture
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.

Robbie is now teaching at Bradley University and working at the Peoria Zoo.

Stephanie Jett  (PhD 2014)

Picture
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 associate professor at Georgia College and State University in Milledgeville, GA.



Zoe Johnson-Ulrich (PhD 2017)

Picture
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. Zoe is now an assistant professor at Eastern Oregon University.

Amity Jordan (MS 2023)

Amity’s primary interest is studying mental health in non-human primates and children. Her long-term research goal is to study how the natural environment affects cognition and change in mental health, not limited to mental disorders, atypical, nonadaptive and stereotypic behaviours . She is also interested in how to eliminate or decrease the frequency and intensity of such observable behaviors in affected individuals. Other areas of interest include emotions, empathy, and the evolution of language and animal communication.
