My research interests are primarily centered on Theory of Mind (ToM), the ability to interpret others' behavior in terms of underlying mental states—a key skill underlying human sociality. More specifically, I am interested in understanding what factors may influence individuals' ability to make these attributions and how this affects our ability to form coalitions, cooperate and coordinate with others.

My dissertation research will explore the role that group membership plays in ToM. I predict that in the right conditions, ToM will show within subject variability similar to empathy: just as we tend to be more empathetic towards in-group members and less so towards outgroup members, ToM assessments will be affected by target individuals' affiliation. Additionally, I predict that ToM will be flexible and sensitive to changing coalitions.

Dissertation Title: Risk management through social networks among Karimojong agropastoralists of Uganda

My dissertation research will investigate how Karimojong agropastoralists of Uganda use their social networks to manage the risks posed by their volatile ecological and political environments. Historically, like other East African pastoralists, Karimojong engaged in livestock and food exchange relationships that carried an implicit obligation to assist partners during hardships such as drought, livestock disease and raiding. Exchange networks played a prominent role in recouping short-term losses such as food shortage, and in ensuring long-term sustainability through rebuilding herds. However, as a result of prolonged, armed cattle raiding, military intervention, and other large-scale changes, such as livestock loss and destabilized intra-group relations, the risk-buffering social networks of Karimojong have become weak. To examine how large-scale changes affect social risk management strategies, I will collect qualitative and quantitative data to address three main questions: 1. How do such variables as wealth, geographic location, and kin relation influence an individual’s personal network of exchange partners?; 2. How do the social network properties of a neighborhood (cluster of households) influence its ability to minimize risk?; 3. To what extent do the norms underlying the current system of exchange differ or resemble the norms of the previous generations? Besides advancing our understanding of contemporary risk management among East African agropastoralists, and examining previous systems of exchange, this project will contribute to theories of human cooperation, reciprocity, and risk management from evolutionary and cross-cultural perspectives.

Human cooperation and exchange, particularly in volatile environments; signals of commitment, especially religion


Agent-based modeling; game theory; genetic algorithms; data visualization


My dissertation consists of several agent-based models (i.e. computer simulations) of human cooperation, including the east African system of osotua, as well as one that attempts to model religious signaling and commitment.
