Post-Doc

    • Evan MacLean

Evan MacLean

The broad aim of my research is to address human social cognitive evolution through comparative studies extant taxa. At present I am working primarily with apes, prosimians, and domestic dogs. My research interests fall into two main categories. The first concerns the evolution of theory of mind, our ability to think about the thoughts of others. I am investigating to what degree we share this capacity with other great apes with the hope of understanding what changes were critical in the evolution of uniquely human cognition. My second area of interest concerns how cognition evolves. What are the selective pressures that influence cognition and do species differ in predictable ways that map on to ecology?

Korrina Duffy

I received a B.S. in Ecology and Evolutionary Biology from the University of Arizona in 2009 and completed minors in Anthropology, German, and Chemistry.  Toward the end of my studies I became increasingly interested in the intersection between evolution, anthropology, and psychology which led me into the field of comparative cognition.  I currently work as the lab manager in the Hare Lab.

Graduate Students

    • Alex Rosati

Alex Rosati

Primates in the wild face complex foraging decisions: choosing the most ‘valuable’ of potential resources to exploit, remembering the location and navigating between widely distributed options, and dealing with conspecifics that are attempting to do the same thing. My research focuses on how animals solve these problems. Specifically, I compare behavioral strategies and psychological abilities in primates--including lemurs, chimpanzees, bonobos, and humans.

Jingzhi Tan

Humans are incredibly skillful in working with others. We cooperate in large-scale for a long term with unfamiliar strangers even in a costly way. However, how human cooperation evolved remains a mystery. Are we ultra-cooperators because we evolved to be genuinely altruistic to others or because we became more trusting to strangers? I study the psychological mechanisms of cooperation and trust in humans, nonhuman primates and dogs.

    • Kara and Napoleon

Kara Schroepfer

My research focuses on the evolution of social behavior & cognition, primarily in apes.  My main interest is in understanding the ontogeny of social relationships, particularly during female-transfer in Pan species where adolescents must leave their natal group and integrate quickly into a neighboring community before they can begin reproduction.  I am also interested in what constrains social behavior in female chimpanzees, such as energetic and nutritional requirements and offspring development.  I approach these questions by combining observational field studies with sanctuary-based cognition and energetic experiments.

My interest is in social decision making processes and the development of social skills in nonhumans. I am particularly curious about the proximate mechanisms that may underlie social interaction such as intention-reading, planning and reciprocity, and how these mediators evolved.

    • Victoria Wobber

Victoria Woober

I am a Ph.D. student in the Department of Human Evolutionary Biology at Harvard University. The aim of my research is to investigate the origins of human social behavior and cognition, including the underlying physiological mechanisms.

My research focuses on humans' closest living relatives, chimpanzees (Pan troglodytes) and bonobos (Pan paniscus). I compare behavior, cognition, and endocrinology in these two species, with the hypothesis that developmental shifts in these traits have resulted in the phenotypic differences seen both within the genus Pan and between Pan and modern humans. I also study domestic dogs as a model for the evolution of human social cognition, with a particular focus on their use of humans' communicative cues.

Undergraduate Students

    • Rachna Reddy

Rachna Reddy

Class of 2012, Evolutionary Anthropology

Rachna is currently working on her senior thesis project in the lab entitled "Behavioral contagion in lemurs."  Her current research is based on some of our group's past research on social cognition in lemurs.  All lemur species evolved from a single common ancestor, but they have incredibly different social systems, diets and habitats. These factors contribute to the evolution of abilities that allow them to interact with individuals in their social groups. Our lab's research has shown that ring-tailed lemurs, who live in large, hierarchical social groups perform better on competitive tasks of social cognition than mongoose lemurs, who live in small pair-bonded groups. In this experiment, we wanted to compare their capacities in a noncompetitive context by looking at whether contagious yawning, a behavior that is contagious in humans and other anthropoid primates, occurs in lemurs. Contagious yawning is considered by some to be a form of emotional contagion and a precursor to empathy. Rachna and her team will investigate whether yawning is contagious in lemurs when they watch videos of their group mates yawning compared to videos of strangers.  Rachna is interested in the complexity of species' social relationships and the cognitive abilities they have evolved to facilitate them. She has helped to develop and conduct experiments that examine social cognition, social learning and inhibitory control in nocturnal and diurnal lemurs and spent last summer observing wild chimpanzees in Uganda.
    • Joel Bray and Sifakas

Joel Bray

Class of 2013, Evolutionary Anthropology


Joel is an independent study student in the Hare Lab working on a project involving social cognition in lemurs.  He is interested in whether lemurs prefer to retrieve food that a human experimenter cannot see.  After finding that ring-tailed lemurs prefer to take food from behind a human experimenter over food in front of the experimenter, he is now testing ring-tailed lemurs and mongoose lemurs in an experiment to determine the types of cues (body orientation, head orientation, eyes) the lemurs are using to retrieve the food.  His research interests involve the following topics: cognitive evolution, theory of mind, social behavior, foraging ecology, human and nonhuman apes, and lemurs.

    • Ben Finkel discussing conservation with children

Ben Finkel

Class of 2013, Evolutionary Anthropology B.S. and Environmental Sciences B.S.

Ben is a sophomore undergraduate working in the Hare Lab. He splits his time between outreach projects and assisting with ecological psychology research. On one hand, he runs studies on the relationship between ecology and decision making in human and non-human primates. A main question is how does evolutionary environment affect the psychology of making risky versus safe decisions? His other project is in education and conservation outreach for the lab. He helps run the Friends of Bonobo blog, Primate Palooza, and fundraisers for Lola Ya Bonobo. His favorite part of outreach, however, is going into local schools to teach about bonobos, conservation, and evolution. He's interested in how evolutionary knowledge can be applied to improve teaching strategies. His general research interests include: conservation psychology, ecological anthropology, empathy, and conservation biology.

Kerri Rodriguez

Class of 2011,  Evolutionary Anthropology, B.S. and Biology, B.S.

Kerri graduated in May 2011.  She spent many of her days conducting research at the Duke Lemur Center and completed a senior thesis project  entitled “How do lemurs remember? A comparative spatial and long-term memory study of ecologically distinct prosimian primates”.  Her project looked at how selective factors, such as food availability or social structure, have led to the neurological differentiation in various species of folivorous and frugivorous lemurs. Specifically, the project compared the strategies used for remembering spatial locations under both short term and long term delays. Her broad research interests include: behavioral ecology, comparative cognition, social behavior, foraging behavior, and cooperation.
