Postdocs


DSC_2308a .jpg

Jan Engelmann is a Marie-Curie postdoctoral fellow. He received his PhD in developmental and comparative Psychology from the Max-Planck-Institute for Evolutionary Anthropology, working primarily with Michael Tomasello. Jan's research focuses on cooperative social relationships. He conducts empirical research with human children and chimpanzees on topics such as reputation management, trust, and friendship. In particular, he is interested in how individuals recruit valuable collaborative partners, how they establish trust, and how they maintain profitable partnerships over the long-term. The ultimate goal of his work is to understand how social relationships contribute to - but also often stand in the way of - a morality that aims at equal treatment for all.


Fan Yang is a post-doctoral researcher at Yale. Fan is broadly interested in the moral and social forces that transform negative self instincts to promote optimal outcomes for individuals and society at large. Fan's recent projects in the SCD lab focus on early expectations and behaviors to promote the common good, as well as how morality is perceived as essential for happiness.

Graduate Students


Ashley Jordan is a fourth-year Ph.D. student working with Yarrow Dunham and Karen Wynn. Broadly speaking, she is interested in how infants and young children think about social partners and group membership. In the SCD lab, her research focuses on how children weigh category-level and individual-level information when reasoning about others’ relationships. Additionally, she studies how social messages from adults impact early preferences for similar others.

 


Alexander Noyes is a fourth-year Ph.D. student working with Yarrow Dunham and Frank Keil. He is primarily interested in concepts-categories and their relationship to causal reasoning. In Professor Dunham's lab, he explores children and adult's causal beliefs about social categories, such as race and gender.

Xin (Kate) Yang is a second-year Ph.D. student at Yale. Her research interest lies in the intersection of intergroup social cognition, cooperation, and morality. More specifically, she is interested in investigating the causes and consequences of intergroup biases, as well as how intergroup thinking interacts with moral reasoning. Ultimately, by uncovering the interplay of group, cooperative, and moral concerns, she hopes to reduce prejudice, promote cooperation, and create a more just world.
