I'm a cognitive scientist and external professor at the Santa Fe Institute. I study decision making, judgment under uncertainty, social cognition, belief dynamics, categorization, and visual perception.
A recurrent theme in my research is the development of new theories and the use of formal mathematical models to try to understand the underlying processes. Another theme is the ecological perspective. To understand adaptive behavior, we must consider how the environment, social or physical, is structured and how psychological processes exploit, or fail to exploit, these structures.
My current work focuses on understanding how properties of individual decision strategies and social network structures affect belief dynamics and group performance by connecting research in social cognition and decision making with insights from physics, statistics, and machine learning.
