Daniel Li Chen is Director of Research at the CNRS and Professor at the Toulouse School of Economics. He is also a Senior Fellow at the IAST and the founder of oTree Open Source Research Foundation and Data Science Justice Collaboratory. Chen was previously Chair of Law and Economics and co-founder of Law and Economics Center at ETH; he was a tenure-track assistant professor in Law (primary), Economics, and Public Policy at Duke University.

Chen received his BA (Summa Cum Laude, Phi Beta Kappa) and MS from Harvard University in Applied Mathematics and Economics (thesis advisor: Michael Kremer); completed his Economics PhD from MIT (thesis advisor: Esther Duflo); and obtained a JD from Harvard Law School.

Chen uses his extensive empirical training to tackle long-standing legal questions previously difficult to empirically analyze. He has attained prominence through the development of open source tools to study human behavior and through large-scale empirical studies – data science, artificial intelligence, and machine learning – on the relationship between law, social norms and the enforcement of legal norms, and on judicial systems.
