CRiSS-LAB is the Computational Research in Social Science Lab at Universidad del Desarrollo in Santiago, Chile, directed by Cristian Candia, Ph.D. We use applied AI, computational social science, network science, causal inference, machine learning, and behavioral data to build rigorous research and decision-support technology for education, school coexistence, business, public policy, civic debate, fraud-risk analytics, and social-impact innovation.
