Motivation and Overview• Goal: create a research program that leads to understanding of social norms,

political change, cultural dynamics, societal stability with a multi-dicsiplinary lens involving network science, systems theory, dynamics, Economics, Political Economy, Computer Science

• Many of the central questions involve interactions among individuals and groups with different identities– Study of collective phenomena and collective decision making in networked setting

with domain specific knowledge– Need more quantitative approaches, beyond descriptive

• Need theory, principled modeling, data analysis, lab experiments, and field surveys

• Need to educate a new breed of computational social scientists and engineers

Why us?• Our team literally wrote the book on the topic
