We are a group of scientists at the undergraduate, masters, phd, and postdoctoral level working on large-scale, system problems in many fields including computational social science, linguistics, mathematics, data science, computer science, fluid dynamics, sociology, nonlinear dynamics, networks, ecology, and physics.

The team was first established over a decade ago by Peter Sheridan Dodds and Chris Danforth. Our alumni bring morally grounded and ethically conscious data science training to their important work in industry, government, and academia.
