Cognition
How can we model the human reasoning process? My new agenda at the Manos Institute is to develop formal models of cognition. Our first papers will be coming in 2026–27.

How people reason.
How groups coordinate.
I study how people reason and how groups coordinate. My research is focused on cognition, where I work on modeling the human reasoning process, and networks, where I study collective action, contagion, and influence.
Research Agenda
Networks
How does interaction shape collective action? I study contagion, influence, and network design: when social structure helps groups coordinate, and when it traps them in bad equilibria.
